I've only done sunday morning sessions so far (-the weekday evening sessions clash with my other classes) which fit in well with my routine and I'd only be lounging in bed otherwise. Guess in the mornings I'm generally fresher than at the end of a day's work so my performance would probably be better am than pm ? :dunno: Given the choice I'd rather train during the day and outside. This time of year daylight is precious and even though I tell myself the days are getting longer it does'nt feel like it on these cold,dark January mornings! Been experiencing some spasmodic lower back pain at the moment so it's ibuprofen,liniment and lots of gentle stretching.Don't know whether it's from work or training-either way it sucks . I've had similar episodes in the past,according to the doc it's always been muscle fatigue built up over a period before a slight movement can cause the locking up-usually sorts itself out after a couple of days,fingers crossed.
