I read on a website tonight that doing 100x religions of squats does nothing to increase muscle mass in the glutes and that it is actually unhealthy. That you should only do 12 - 15 reps at most. I am more than halfway through this challenge and wondering if anyone has any insight into this. Thanks a bunch! :)
Doing many reps of little weight will never increase muscle mass for any lift, only muscle endurance. The best way to increase muscle strength is by lifting heavy 3-5 sets of 3-5 reps where the last rep should almost be failure. Muscle mass (body building style) is gained by lifting add much as you can for 3-5 sets of 6-10 reps where the last one should almost be failure again.
Thanks so much. Guess I am gonna abandon the challenge.
