"Should I train while I'm ill?"
It is a question that my clients often ask me & my answer is always, 'it depends'.
The easy answer is that I don't want anyone to come to train in my gym if they are ill because of the risk of passing it on to me & others but the fact is that we are often infectious before we start feeling unwell. Hindsight is very often the thing that tells us we shouldn't have gone to the gym, into the office or to visit great aunty Maggie. Life happens! And while it is a good idea to try to limit the spread of infection we just can't eliminate it & live any kind of normal life. And we have all had too many experiences in recent years of what abnormal life looks! Let's not go there again...
So, the most important thing to consider is whether training while your are ill is good for you or not. And that requires you to weigh up the costs & benefits of training or not training & to pay attention to your body & adjust your plan if you do decide to train. And that's what I've had to do over this past weekend.
I started to feel like I had a cold coming on Wednesday evening; just the first ni**le of a cough. On Thursday I knew I had a cold & even though I felt ok, I opted out of my evening cycling club ride in the hopes that I'd feel better on Friday & Saturday (because I had bigger rides planned on those days). Friday came & I didn't feel too good so did no exercise at all (though I did go out to Asda & lunch, so I wasn't suffering from full-blown man flu!). I felt ok enough to ride 35 miles on Saturday but it was a much shorter & less challenging ride than I really wanted to be doing, even though it felt much harder than it ought to.
Sunday I felt pretty grotty again, though I did manage a decent walk for an hour.
And today I was in the gym doing my scheduled weekly strength session. Or that was the plan anyway. I got stuff done but it felt harder than usual so I backed off. Initially I thought I might just run through my warm-up routine & stop there but I ended up doing one working set instead of my normal two & dropped my working weight down for all of my lifts. Deadlift was my last exercise & warming it up didn't feel great so I settled for doing a single heavy lift (instead of a heavier set of five) & calling it a day. I don't know if I was just being a wimp or whether my back was indeed sending me a warning signal but I chose caution over my programme.
After lifting I went for a short walk which felt fine but was slower than normal. And now, later in the afternoon, I feel moderately wiped out.
Was it a good idea for me to train today? On balance, I think it was but it was also very right not to push too hard. I'm clearly getting over my illness (it really hasn't been that bad) but I have learned to respect that fact that when I'm ill I need time & energy to recover. Training hard takes up that time & energy & prolongs my recovery so it just isn't worth it.
Now, if I was training for a specific competition on a particular day I might just have to push harder in my training but life has taught me that often doesn't work out well, though sometimes you have to take a gamble. But I'm not training for a competition, I'm training for my life & my health & there is no point on pushing myself so hard now that I can't function in the future.
The general rule I apply is that if you have a head cold (sore throat, blocked nose & sneezing) then you are probably ok to train, if you want to. If you have a chest cold (coughing & mucus) then just give yourself a few days off. But if you are running a fever, are achy & shivery and/or have an upset stomach or gut, you need to let yourself rest to recover. Mild headaches can be treated with paracetamol & worked around but anything more than that deserves rest & recuperation.
If you miss a week of training you'll barely notice the effect on your performance. And if you are feeling feeble & can't train to full effect, you are not really getting benefit from the training anyway while it is costing you time & energy. Pushing too hard instead of allowing yourself downtime to recover from illness just runs the risk that what might have taken a week out of your life morphs into a more serious illness (a chest infection, perhaps) that badly affects you for months to come.
But if the idea of doing no training at all (lifting, running, cycling, etc.) is too much to bear, then go for a walk. Walk as much as you want but don't push yourself through fatigue. It just isn't worth it & it really doesn't benefit you at all.
Anyway, it turns out that my mild head cold is actually COVID. Colds actually seem to floor me more than COVID does but I'm not about to mess with an illness that has caused friends, relatives & clients some long-term problems. But all illnesses have the potential to produce long-term problems if you are unlucky enough or manage them badly.
I'm in the business of trying to help people improve & manage their health not about maximising their short-term athletic performance. My clients know I provide hard, demanding training but they also hear me tell them to rest hard too. After illness, injury or surgery, I believe it is important to get back to hard training but it needs to be balanced with rest if you want to achieve task recovery. It is a lesson I keep trying to learn myself! Maybe one day... (Do as I say, not as I do...)
