Hey there. I'm doing a bit of strength exercises, 40 minutes 4 times a week, my equipment is my body, some furniture and a pair of dumbbells, I try to eat well ...
My goal is to put on some more visible muscle and gain strength, however I'm not in a hurry with the muscle-thing, so if I get some strength - and the muscle in the long run - I'll be happy. My problems/questions are:
1. Should I do my exercises as fast as possible (still in a good form) or should I take my time? Does it depend on the exercise? (i.e. doing pushups with 2 seconds down, 1 second hold, 2 seconds up should be better for me, but is this also true for biceps curls?)
2. How long should I rest between sets?
3. I do 15 reps/3 sets for most of the exercises, are there muscle groups I should train with a different number of sets/reps?
