Unfortunately it was my fault - driving too fast on wet roads and went into the back of a van. I managed to slow down but my friend who studies medicine told me whiplash is actually worse when you have time to prepare for an impact.
I've taken a week and a half off and am now slowly moving back into my routine, minus back and shoulders for the moment. Still have a bit of pain in my neck so will try and take it easy but its difficult when you are used to a gym mentality that laziness and lack of commitment are to be combatted.
D-bol -
I agree that time off is neccesary, from what I've heard not only the muslces but also the central nervous system needs a break, however I would struggle to stay away from the gym for a month - I just get bored.
Soundness -
I train alone, so training to failure can be risky on, for example, bench press but what I usually do is to aim for 8 reps a set and then end up doing 5-6 on my 4th or 5th set.
I've heard your gains can substantially increase after a break before, so fingers crossed.
Thanks for th info / tips guys.
