My martial arts instructor has been haranguing us about the importance of conditioning etc. so I'm currently working my way up on an endurance lifting programme, doing curls & presses with a comparatively low weight (20kg + bar) on 4-6 sets of 15-25 reps... I decided to do endurance lifting because power lifting is only recommended on an alternate day basis and I want to lift every day (although if we've had a hard session at training I might be tempted to skip a workout and just have a shower and go to bed!)
Anyway, I was curious as to what strain this was putting on my elbow joints, and whether higher reps on a low weight were more or less likely to cause joint strain than lower reps on a high weight (i.e. power lifting.)
Does anyone have any studies they can point me to? Or medical knowledge, personal experience etc.?
