Is it normal to feel significant pain in certain muscles when you first start exercising?
If we consider a pain scale of 0 – 10, a maximum of 3 out of 10 is acceptable. Another useful rule is that you can expect to feel equal pain on each side of your body. Muscle pain that is significantly worse on one side than the other may indicate something more significant than muscle soreness and therefore needs to be watched carefully and assessed if persistent.
What is actually happening to your muscles when you feel sore?
It’s generally accepted that the old “lactic acid” theory no longer holds true. Lactic acid, which is produced in the muscle as a result of not being able to get enough oxygen to the muscle fibers due to a high exercise intensity, is cleared from the muscle very quickly. So it cannot be responsible for the pain that worsens over a two-to-three-day period.
So what’s the real cause?
Current theories suggest that “delayed onset muscle soreness” – or DOMS – is the result of an inflammatory response due to the microscopic muscle damage that occurs during exercise. It sounds bad, but it’s this microscopic damage that leads to the adaptation within muscle – this is one of the reasons exercise is so good for us. This damage stimulates the muscle to respond by laying down more muscle fibers (increasing muscle tone) and improving the blood supply to the muscle (capillarization), so there is less damage next time we train. Capillarization makes it easier for the heart to get oxygen to your muscles, which is how exercise makes you fitter and improves your blood pressure.
What’s the secret to minimizing pain at the outset?
If you’re just starting out or reigniting your fitness journey, the secret is to start slowly and increase the frequency, duration and intensity of exercise gradually over a six-week period. This is why the Smart Start template works so well – it’s designed to minimize muscle soreness and allow the adaptation process to occur with minimal discomfort.
We’re told to warm-up and warm-down, but can you do more to avoid strain or pain?
Know your limits during a workout. If you haven’t curled a bar for a long time, chances are your biceps aren’t going to be too happy when you suddenly subject them to bicep curls for a whole track (which may consist of around 100 reps) in a BODYPUMP™ class. Similarly, you may walk upstairs every day at work, but if you haven’t done anything resembling a jumping lunge since primary school, your quads probably aren’t going to be happy after your first BODYATTACK™ class. All Les Mills instructors are trained to give options as they coach the workout to make this easier and less painful. Put your ego on hold and take the options. Your muscles will still gain the benefit without the soreness.
I’ve swum for years and am in reasonable shape, but BODYPUMP really left my triceps sore for a while – why?
Swimming is great exercise, but it’s very different to lifting weights. Muscles develop memory from training. If you haven’t done tricep extensions before, all the swimming in the world won’t help. Lifting external load during a tricep extension will challenge the fibers in a very different way to a swimming stroke. The result is muscle breakdown and inflammation. But don’t despair – muscles adapt really fast at any age. Give them time and they will lap up tricep extensions with ease.
Should you get back into it even though you are still sore from exercise?
Repeating the same exercise that produced the sore muscles prior to recovery is a little risky and probably won’t seem like a good idea anyway. However, if you are suffering from upper body stiffness as a result of training your arms, chest and back, some leg training will probably be fine. And low intensity cardio training may even help speed up the recovery by flushing oxygenated blood through the recovering muscles. You could try a low intensity RPM™ class the next day, maybe.
Is a little soreness always part of pushing yourself to the next level?
Elite athletes have an amazing capacity for pain during and after exercise – in fact they crave it. And yes, if you have to improve performance by very small increments to become the world’s best, at times it’s going to hurt. As for the rest of us, it doesn’t need to hurt at all, so why push it that hard? When I train I think, I’m going to be doing this for years, so what’s the point in busting a gasket now?
Finally, will stretching, rubs, hot baths or saunas really help muscle soreness?
Go easy with stretching when your muscles are sore. The inflammation makes them sensitive and an aggressive approach to stretching won’t make them recover any faster. Rubs really won’t help either. Hot baths are okay if you need to get clean, but they won’t help – even with Epsom salts. (Just don’t tell my mother.) Saunas, again, not a lot of help for muscle pain relief. My advice? Go for a walk!
