to all who can offer some help. i have come to a stand still and wonder if it is the amount of reps im performin. i cant seem to gain any strength. i am doing sets of 8 and on the last set going to exhaustion. i was wondering if i should lower my reps and perform those at a higher intensity? also what if i worked chest twice a week and on one of the days doing low reps while on the other doin high reps with light resistance? one last question if i do lower my reps should i complete all three sets completely or should i have to lower the resistance as i climb in sets? thanks to all!!!!!!!!
