Tom8521 saidI'm not sure.
The first time I worked out, I was told I worked too many muscle groups at one time. The next day, I could barely move.
This time I have been more selective, but don't think I will the workout will even be remember tomorrow.
It's confusing me now. Should I lift a crazy heavy weight just a few times, or a not quite so heavy weight many times?
It really depends upon what your workout goals are.
I tend towards fitness, sustainable strength, and form. Some people seek bulk, burst strength, and other goals.
I tend to work out to failure and generally enjoy "delayed onset muscle soreness" (DOMS). I like just enough ache to let me know that I had a great workout. I don't want the kind of ache which results from overworking or injuring any muscle.
Don't forget to work core. Don't forget to stretch both before and after your workout.
