Almost all non-impact injuries, not all, are because of a change in your routine.
* you started back too much, too soon following a lay-off
* things were going well in training so you increased too much
* added too many variants all at once
For example, you exercise regularly but you had a lay-off due to a holiday or illness, say a week or two. When you're ready to return, you don't start back gradually with less workload, less regularity, but instead go right back to where you left off. Your body has become 'de-conditioned' and therefore, you overload it and it breaks down.
Or, the weather breaks and the sun comes out. You haven't touched the garden in months due to bad weather. You decide to make the most of things and get out into the garden and spend 6 hours weeding, bent over trimming edges, reaching above to cut tree branches. Again, your body hasn't done this work for several months and you overload it.
You have been training really well for some time and are really fit. You think adding in some extra training will bring even better results. You've been running or going to the gym 4 times per week, so decide to up that to 6 or even 7 days per week. you also increase your workouts from 45 minutes each to an hour and a half. It's just too much for your body to handle, so it breaks down.
Similarly, you've been going well and you add in too many variants. Maybe you've been running 4-5x per week and just coming off the winter where training has been steady slogs. You introduce some hill reps, you start generally running faster with either tempo runs or sprints. You increase your training to 7 days per week. You increase your long run from 10 miles to 18 miles.
Too many variants. Training is about your body adapting to load. You apply too many different loads and it cannot cope. You apply a single increase and allow yourself to recover, you're body will adapt.
Only add a single variant at a time. Adapt. Then choose another variant. Amount, duration, recovery (reduced), intensity/speed - only increase one at a time...
