Every year I tell myself I am gonna get into shape for the upcoming summer and it never happens. This year I plan to change that. I am about 5'11'' and 145 lbs. Typical tall, skinny, 19 year old kid. The past few days I've been doing crunches and push ups. So now I want to know, if my muscles are sore is it better to let them rest and work on something else, or continue exercising? Also if anyone has some good workouts that don't require any large pieces of equipment, I would really appreciate it.
