I'm trying to increase my muscles so I've been doing about 200 pushups (in 10 sets of 20), 200 dips (excercise where you place your legs on a chair or bench and your palms on a chair opposite and touch your ass to the ground and push back up), and like 60 crunches. I've noticed my pecs getting bigger as well as my biceps and triceps but is that enough or should I add any other simple excerises, my university has a brand new rec center i plan to use sometime but havent gotten around to it yet.
Is this enough?
Definitely hit the gym. Using the machines is a lot less tedious than pushups, etc. Plus you get very good control over what gets exercised, and you can fine tune your program, if you're obsessive.
When you do your dips put some weight on your lap i put on 75 lbs and do it 3 sets 10 reps as like my power workout, or i put on 45 lbs and do 5 sets 15 reps and also start bench pressing, butterflys, curl and all that good stuff.
