The Importance Of Rest Days

Getting in your workouts and nailing your nutrition is crucial when it comes to achieving your fitness goals – we all know that. Chances are you take the time each week to schedule in your training sessions and think about what your meals are going to look like. But are you also planning your rest and recovery?

Adequate recovery time is hugely important, but it’s all-too-often overlooked. And this is true of everyone – fitness junkies sometimes dismiss rest as unnecessary and boast that they train hard every day, while on the other end of the scale, fitness newbies may feel they have some catching up to do and end up setting themselves ambitious aims to train hard five, six, seven times per week to maximise their progress.

But in reality, everyone – whether they’re new to fitness or have been training for a while – needs to give their body enough time to rest and recover. It might be tempting to go all-out, but rest is a crucial part of your training. If you’re wondering why, keep reading.

Allow muscle recovery and growth

Anyone who has challenged themselves in the gym will be familiar with DOMS – muscle soreness and stiffness that lasts for a couple of days after a tough workout. This pain because exercise creates microscopic tears in our muscle tissue that occur when we work out. It’s a completely normal part of the muscle growth process – it is when these muscle tears knit together and repair that the growth and strengthening occurs.

These small tears naturally start to repair when we stop overworking them. The muscle fibres compensate for the damage by physically re-building themselves to be bigger and stronger, so that they can cope better with the stress from an exercise routine in future. Refusing our body the chance to recover therefore means compromising our muscle’s ability to grow.

This is where workout splits can come into play if you’re lifting heavy on a regular basis. Put simply, this means staggering your workouts in such a way that allows you to vary the muscle group you’re working, so that each one has a chance to rest before being exerted again. When you train with us at Fitness Labs, one of the first things your coaches will do with you is to sit down and chat about your goals and your current schedule. They will put together a personalised workout plan that optimises your ability to reach your goals and will factor in adequate rest time, to make sure that you don’t overtrain.

Reduce your risk of injury

A really common consequence of overtraining is injuries. If your body is refused the chance to repair after intense workouts, it could lead to weaknesses and injuries that prevent you from training properly. Overuse injuries can be avoided by giving your joints and muscles the time to rest in between workouts. The rest time you need will vary depending on the type of training you’re doing and how experienced you are when it comes to fitness – don’t worry, your coach will be there to guide you through this!

Immune system health

Regular exercise has been shown to boost immune health (for example, studies have shown that people who exercise regularly have a higher number of the bacteria-attacking cells called macrophages). However, intense exercise does put your body under a certain degree of stress, so it’s important not to overdo it. When it comes to your immune system, there are a number of ways over-exercising can impact you. Notably, our bodies’ stress hormones (cortisol and adrenaline) raise blood pressure and suppress the immune system. This has been linked to a higher risk of infection in endurance athletes after extreme exercise (e.g. triathlons).

Ensure you enjoy your workouts and prevent burnout

There are lots of physical advantages to prioritising rest and recovery, but it’s equally important to consider your emotional and mental wellbeing, too. Mental fatigue can be just as draining as physical fatigue, and taking a rest day can help to rekindle your desire to train, making sure that your training stays FUN.

You should never feel as though you’re having to drag yourself to the gym – if that is the case, then it’s a sign that you’re tired and need a day to reset. Enjoy a rest day or two, then come back strong and find the fun in your workouts.

Create sustainable fitness habits

Arguably the most important factor when it comes to achieving your goals is consistency, with both your nutrition and your workouts. So, you need a level that you can sustain – you might manage a couple of days of hitting the gym at max effort, but pretty soon you’re going to burn out. Balance out higher intensity workouts with steadier sessions, stretching and complete rest days.

If your workout regime isn’t sustainable, you won’t stick to it, which means you won’t see results. This can lead to a vicious cycle of bursts of intense training, burning out, loss of motivation and periods of not doing anything, before again picking up an intensive new regime that you will ultimately abandon. Stick to a steady-paced programme that you can maintain, trust the process and the results will come in time.

Can rest days help with weight loss?

If you’re focused on losing body fat, it can be tempting to just forget about rest days and concentrate on burning calories at all costs.

The trouble is, ditching your rest days does come at a cost. A lot of the time, this cost impacts your body’s ability to burn the fat that you’re keen to get rid of.

If you approach exercise with a ‘no rest days’ mentality, you’ll likely end up increasing the amount of stress hormones in your system. Stress hormones – in particular ‘cortisol’ – can do all manner of damaging things to your ability to burn fat. If you’re experiencing poor sleep, an increased tendency to snack, and a lack of focus, it’s possible that cortisol is at least partly to blame.

Personal Training London

As we’ve already covered, it’s important to incorporate rest days to make sure you’re building muscle effectively. Even if you’re not weight training, adding muscle to your body is the single most effective thing you can do in the gym if you want to burn fat.

This is because muscle requires energy just for maintenance. The more muscle you have, the more calories you burn at rest. Therefore, anything you can do to encourage growth of your muscles makes you an even better calorie-burning machine. What’s better than burning calories while you rest?!

How many rest days per week should I take?

It really depends on how long you’ve been training and what type of training you do. There is no one-size-fits-all. You might be able to tell that you need a rest day before you next workout because you feel too tired to get through what you normally can. Maybe you feel like you’re having to drag yourself to the gym, whereas you’d normally leap at the chance to do a workout.

The best advice – as with so many things related to health and fitness – is to take the time to get to know your body and listen to what it tells you. Understanding what too much exercise feels like and how much rest you need is an important part of staying healthy.

What to do on a rest day?

Taking a rest day doesn’t necessarily mean spending a day glued to your sofa, binge-watching Friends and eating aaaaaall the snacks (as good as that might sound).

Instead, it’s worth understanding what an ‘active rest day’ is. This is a kind of active recovery that might mean going to a relaxing yoga class, or still going to the gym but avoiding high-intensity or heavy workouts. You could warm up and go through mobility drills or stretches, or skip the gym entirely and go for a walk, gentle swim or cycle. Low impact exercise still counts as rest (“active rest”) and, crucially, getting enough rest can be good not just for the body for the mind, too.

We’ve explored some rest days ideas in our dedicated blog: What Should I do on Gym Rest Days?

What should I eat on rest days?

There’s no blanket rule around what you should eat on rest days. Ultimately, the answer depends on what your health goals are. Beware of any source of information that says you should always cut your calories on rest days – this simply is not true for most people.

If your only goal is fat loss, there may be some merit in reducing calories while you let your body recover.

However, if you’re looking to build muscle at the same time as reducing fat (one of the most effective ways to do so), then reducing calories on rest days can counteract your goals somewhat.

Of course, there are lots of people who train with the goal of bulking up. For people with this goal, you may even want to look at increasing calories on rest days.

So, as you can see, there’s no one-size-fits-all answer. Recovery days – like your workout routine – should be tailored to you.

Strength And Getting Older

It is estimated that people lose around 3-5% of their muscle mass per decade after they reach 30, with this rate of decline higher in inactive individuals and accelerating in all of us after the age of 60. This loss of muscle mass and strength is a serious cause for concern, as it contributes to the overall increased frailty and reduced mobility that can strike in advanced years, both of which lead to a higher risk of falls and injuries.

Why do we lose muscle in old age?

There are a number of factors that contribute to age-related muscle loss, a phenomenon which is also referred to as sarcopenia. As we grow older, our muscles become resistant to normal growth signals (nutrition and exercise), in a process known as anabolic resistance. When studying the muscles of older individuals, we do not see the normal increases in muscle protein synthesis (the repair and growth of muscle tissues) after exercise. Although this phenomenon is more common in older populations, it is becoming increasingly common in younger people, a fact that is likely caused by our steady decline in physical activity and increasing rates of chronic inflammation (which is itself a major contributory factor to muscle loss).

Other causes of muscle loss as we age include hormonal changes, specifically of those hormones that have a role to play in muscle mass maintenance, including testosterone and oestrogen.

The menopause and muscle loss

While age-related muscle loss impacts both men and women, women are particularly vulnerable. Studies have shown that after the menopause, the loss of muscle force relative to muscle mass accelerates at a much faster pace than in men of the same age.

This is primarily due to a steep decline in the release of ovarian hormones, with the decrease in oestrogen playing a key role in the loss of both muscle and bone mass. A decrease in muscle mass exacerbates postural issues and contributes to the deterioration of bone health, both factors which increase the risk of osteoporosis (a medical condition in which the bones become brittle, fragile and prone to fractures).

The oestrogen deficiency that occurs around menopause coincides with other lifestyle changes that often appear as we approach our later years. Most notably, levels of physical activity tend to drop, causing us to become more sedentary. As fitness becomes less of a priority, poor nutrition habits may also start to creep in. Combined with the poor sleep quality and high stress levels that many of us are facing across all age groups, we have a “perfect storm” for not only muscle loss, but also fat gain. The result is the loss of muscle tone and weight gain around the middle that we often see in middle age and beyond.

Countless studies have shown that across all age groups, women are consistently less physically active than men and participate much less in resistance training, which will accelerate their already higher rate of muscle loss and place them at an even higher risk of losing muscle mass, experiencing weight gain in middle age and ultimately suffering from increased frailty due to poorer bone health in their advanced years.

Can we prevent losing muscle as we get older?

Losing muscle is generally accepted as an unfortunate, but normal, part of the aging process, however that does absolutely not mean that we are powerless to stop it. While some of the factors that contribute to age-related muscle loss are largely beyond our control (hormonal and neural changes), all the evidence agrees that it is massively compounded by inactivity and poor nutrition. Meaning that there is a great deal that we can do to maintain our muscle as we get older. Studies have also demonstrated that we can continue to build muscle well into our eighties (!) so it is absolutely never too late to start.

The importance of resistance training 

Working with weights in the gym is hugely beneficial across all stages of life, but it should remain a key part of our exercise regimes in later years. As our muscles become less responsive to normal growth stimuli, regular resistance training can help to counteract this and encourage our body to maintain muscle mass. Resistance training not only serves to build muscle, but also to burn fat, meaning that we can help to optimise our body composition well into our retirement.

When it comes to maintaining bone health, weight training again has a huge role to play, with a higher rate of bone formation associated with mechanical loading. Frost’s mechanostat theory was the first to propose that bones will grow stronger in response to stress, and stated that “the bone possesses an inherent biological system to elicit bone formation in response to high mechanical strains, thereby strengthening the bone”. His theory, which has been supported by a large number of studies, suggests that bone formation is site-specific, in other words it is increased in areas of high strain.

This kind of research is highly relevant when we consider the menopause and high prevalence of fractures caused by osteoporosis. One particular study looked at postmenopausal women and concluded that resistance training successfully reduced bone loss in the hip and spine. Hip fractures are one of the most debilitating and life-changing injuries in later life, as they almost always have a severely detrimental impact on independence and quality of life. Weight-bearing exercises that elicit physical loading to the lower limbs can therefore promote bone strength in the hip region

Key takeaways

The decline of skeletal muscle with age is one of the key causes of functional decline and loss of independence in older populations. Women are particularly vulnerable to the effects of this, primarily due to the steep decline in oestrogen that occurs around the time of the menopause, triggering deterioration of both bone strength and muscle mass.

Resistance training benefits us at all stages of life, but it should remain a key part of exercise regime in later years. As well as maintaining muscle mass and strength and promoting strong and healthy bones, resistance training has a positive effect on body composition, hormonal and stress regulation, sleep and cognitive function.
