Should you workout twice a day?

A recent UK announcement clarified that people would be allowed to workout an ‘unlimited amount’ outdoors as part of the gradual easing process of lockdown. Whether you agree or not that this should be allowed or encouraged, it’s led to a spike in articles preaching the benefits of working out twice a day.

For the vast majority of the population, however, working out two times a week would be more than their usual. Is promoting double-days sensible, and is it a tactic that could work for many? Here are some of the pros and cons of working out twice a day.

Pros

  • Double workouts can allow you to fit in more ‘accessory’ workouts, strength and conditioning and physio sessions, reducing imbalances and weaknesses. Some people feel they don’t have time for these if they’re aiming to train 5 days a week and fit in sufficient rest days. Doubling up means you can do an intense session in the morning and a low intensity stretching or physio session in the afternoon.
  • Doubling up but doing the same number of workouts per week can mean that you allow yourself more rest days. Rather than working out 5h a week over 5 days, you can do 2 double days and a single day in just 3 days, thereby allowing yourself 4 rest days a week. You will need them!
  • Splitting a session in two and doing half in the morning and half in the afternoon means you’re able to do each part of the session with more intensity, as you’re better rested for the second half.
  • Splitting a session in two can also allow you to fit it in on a busy day. 30 minutes in the morning and 30 minutes after work in the afternoon is sometimes easier than an hour all at once.
  • Working out twice a day reduces your sedentary time. We know that sitting for long periods of the day can be incredibly detrimental to our health, so even fitting in a short workout morning and evening can mean moving more overall.

Cons

  • Even splitting the same workout in two can lead to injury or overtraining, as you’re working already fatigued muscles. If you’re not used to training a lot, working out twice a day will take its toll.
  • Overtraining compromises your immunity, leaving you more vulnerable to even small illnesses. 72 hours after a long run, your immunity is reduced. For obvious reasons, this is especially problematic now. Doubling up leads to a greater likelihood of overtraining, if not done correctly.
  • Workouts lead to micro tears in our muscles. Doubling up workouts can mean that these tears are not given sufficient time to repair, potentially leading to injury.
  • Running has such a high injury rate that all runners are advised to increase mileage and intensity slowly. Doubling up can mean that it is possible to do more mileage, quicker, leading to common injuries such as shin splints, ITBS, plantar fasciitis and tendonitis.
  • It can be hard enough to convince yourself to get out once a day. By trying to force yourself to head out twice a day you can take all the fun out of exercise.
  • Doubling up is unsustainable for many. Overdo it and you may need to take off significant amounts of time, reducing any benefits you get from your double days.

 

In my opinion, there are more downsides to working out twice a day than there are positives, for the vast majority of people. I have been receiving a record number of messages about people picking up injuries from suddenly increasing the amount they are running, or starting new training programmes without a strong baseline of fitness.

Of course, there will be people who thrive off doubling up workout sessions, especially those who do so with the help of a coach, or who are already experienced in their sport. With proper planning, double days can allow for longer periods of rest between workouts, aiding recovery. They may also help people fit in enough strength and conditioning sessions that they could not otherwise, whilst also fitting in rest days.

The best way to be able to gain all the benefits of working out, even getting fitter during lockdown is to work on one thing at once. If you’ve taken up running, don’t increase intensity and distance in the same week. Your mileage should increase by no more than 10% week on week to avoid injury, but if you do your longest run one week, don’t also start adding in sprints or intervals sessions in the same week, or even the week after. Most of the sessions we do should be at moderate intensity – we do not always need to be pushing the boundaries of our ability. Be kind to yourself – this is a tough time for all and putting your body under extra physical pressure may cause you to reach breaking point.

Perhaps you want to start taking advantage of double days because you’re lacking time or want more rest days. That’s absolutely fine – maybe just try one double day a week (thereby taking one extra rest day too) and see how you get on. Take it easy and remember that recovery (and food) is as important as the session itself!

TL;DR

  • While exercise can improve mood, fitness and your immune response, too much exercise can have exactly the opposite effect.
  • If you are not a professional athlete or highly experienced with a well thought-out training plan, double days are probably going to increase your risk of fatigue, injury and may dampen your immune system.
  • Provided you are not doing more workouts per week, double days can be effective when linking together a S&C session/physio session and a short run.
  • As ever, stick to the 10% rule. If you’re a runner, increase your weekly mileage by no more than 10% per week. Any more than this increases your risk of injury, even (or especially) when taking on double days.
  • Overtraining often takes several weeks to take its toll, so watch out for signs of it, and read this blog post to know when you may have pushed it too far.
  • Listen to your body! If your workout doesn’t perk you up and you feel constantly fatigued, take an extra rest day. Yes, we have a lot of time at the moment and exercising can feel like a welcome break, but the consequences of overdoing it can be serious and long-lasting. Be sensible!

Shin Splints – what are they?

With so many people taking up running since lockdown, the number of physio-related questions I receive over on my Instagram has increased exponentially. One of the most common questions I’m asked (at least once a day at the moment) is how to cope with shin splints, an issue common with runners, especially those increasing the amount of running they are doing too quickly.

As someone who isn’t a physio, I never feel comfortable answering these questions (aside from giving personal advice and opinions on injuries I’ve personally experienced), so instead have asked my physio Zoe from Physio Motion to write something to help you all out. I understand that not everyone can afford/has access to a physio, so I hope this helps! That being said, if you continue to struggle with injury even after rest and rehab, I would really recommend getting in touch with a physio to ensure you’re treating the right issue, and that the problem isn’t something bigger.

Without further ado, onto Zoe! If you enjoyed this post, please do share and tag @physiomotionlimited and @foodfitnessflora so we can see 🙂

Zoe and me on a run in Hyde park

What are shin splints?

Shin splints is a generic term that describes any disorder that causes shin pain.  This historically would be called medial tibial stress syndrome.

It is typically found as pain along the shin bone (anterior tibia), which will settle with rest but will reappear when you start running again and at worse when walking.

With all of these conditions that cause shin pain, it is typically due to repetitive strain injury that is common in runners when they are starting to run or suddenly increase their amount of running.

The characteristics of shin splints can also be an identification of different conditions.

 

What other conditions can have shin splint characteristics?

It is important to know that it could also be due to tibial stress fracture (break within the bone that doesn’t move) or compartment syndrome (high pressure within the muscle caused by swelling).

 

How can I distinguish between these conditions?

If it is true shin splints, the pain will subside with rest and slowly build up again if not managed adequately. Also, people that have just started running will notice that the pain improves over time as your legs get used to the new loads being put upon them.

With stress fractures and compartment syndrome, however, the pain is persistent or can get progressively worse.  If your pain does get progressively worse, it is a good idea to seek medical advice and investigations in order to rule out a stress fracture or compartment syndrome.

 

Why have I got shin splints?

The main cause for shin pain is the load that you are putting through the lower half of your leg when running, and that you do not have the capacity to manage these loads.  This could be due to increasing your training too quickly; increasing the running speed; or inadequate rest periods between your runs and other training.

There is no evidence that a certain type of running footwear will stop you getting shin splints, but if you have been using the same trainers for many years and they are hanging off your feet it might be an idea to treat yourself to a new pair.

 

Do I need to stop running?

For most people you can continue running, but you need to return to running a distance, speed and frequency that previously did not cause you problems. 

If you are new to running then it might be better to start with slow interval running (run walk, or run stop run) and build up the duration that you are running in each interval before continuously running. 

If you are still getting pain then it maybe necessary to stop running for a short period and swim or cycle instead for this period in order to maintain cardiovascular capacity. 

 

What can I do to help with my shin splints?

As shin pain is due to overloading the legs, you need to make sure that the legs are strong enough to absorb running forces.  Therefore, you need to have a strengthening regime to ensure adequate strength in your calf complex, but it is also important to increase the strength in your gluteals and thigh muscles.

We would recommend exercises such as calf raises, slow step ups and bridges, athough we always assess our patients for areas of weakness in the lower limb and tailor a programme to their needs.

Due to the shin pain you can get a secondary response of tightness in the calf.  You can stretch this out, but it will only provide you with temporary short term relief until you start walking and/or running again.  It is more important that you make sure you find out what is causing your shin pain in the first place. Failure to do so could result in a stress fracture or compartment syndrome.

 

What can I do to prevent reoccurrence of shin splints?

When the pain has completely disappeared at the running mileage that is comfortable or after a period of rest, you need to think about how you progress your running programme. Typically coaches recommend 10% increases, but something to remember is that this doesn’t have to be every week and also every run doesn’t have to be to your maximal capacity.

It is also important to have strength and conditioning days, and recovery days in your training regime.

As shin splints are now categorised as a bone stress response, it maybe worthwhile looking at whether your vitamin D and calcium intake is adequate for bone recovery, especially when you start running during the winter or at the start of the spring, when it is shown that vitamin D especially is low for us Brits!

 

How long will it take me to recover from shin splints?

It can take between 6 weeks and 6 months to make a full recovery from shin splints depending on the severity of the condition.  So it is important to be patient and consistent with your treatment and advice given.

 

If you’re currently experiencing injuries, you may find this Q&A vlog with Zoe interesting, as well as this chat with my coach, where we cover running injuries and the importance of recovery, especially in such a stressful time.
