Currently I go to the gym about 4 times a week and do a very basic workout. I hit about all main muscles in my workout. Currently I do about 3-5 sets of 10-15 reps. Depending on how I feel. I want to get my muscles bigger and stronger. What would be a good rep/set routine I should be doing...?? When I first started I tired 3 sts of 10 starting with my heaviest weight I can do and going down 5 lbs with every set (135,130,125) and I tired a reverse of that starting with light and going up to heaviest... but I just stuck with my heaviest weight and do about 4 sets of 10. I was looking into a compression system also 5x5, 10x10, and 6x6.. what would be good for gaining strenght and gaining size?
