I seriously hope you aren't teaching your students this, because it's absolutely 100% wrong!!!ccrunner609 wrote: One poster mentioned heavy weights and low reps......that is completely wrong. Building muscle is Lower weight, higher reps.
Make sure that you are giving your muscles full recovery between days of use. Tear that muscle down and let it grow back bigger before ripping it down again.
I always did a routine where I had 4 days break between using any specific group. 100+ reps per session per muscle group using sets of 12-15 reps and at least 3 different lifts to hit those muscles.
You have to switch up your lifts to get your muscle to respond, you have to change up your hand positions do hit the complete muscle.
Light weight/high reps lead to light to no tears in the muscle, where as heavy weights/low reps lead to large muscle tears and that in turn leads to building muscle! What you will get with low weight/high reps is leaner muscles and a higher tolerance to the lactic acid build up.
In order to tear the muscle, you need the heavier weight!
