| Thanks for the replies. I have been doing 10 exercises in one workout, yes. Is this too much? Believe me, I wouldn't mind doing a little less!
I want to make sure I'm really working lage muscles because I figure if I enlarge the larger muscles, they will burn more calories than the smaller ones.
I had been doing 3 sets of 12 reps for most everything I've done in the past, but had recently begun to add more weight and do between 6 and 8 reps.
My concern with the squats is injuring my lower back by not having the correct form. I know what the correct form is; I'm just worried I won't achieve it. When I do squats without weights, I hold out my arms straight in front of me and that helps steady me. When I use a barbell or dumbbells, I fell less stable. I guess it's just a matter of practicing.
If anyone would like to recommend a routine based on my goals, I'd be happy to try it out! Thanks. |
