I need a good workout to get back in shape?

Back in December I had a surgery on my rib cage, which left me unable to do any workouts until just recently. Needless to say I lost a lot of muscle. I'm exactly 6'00'' tall and weigh around 150lbs. I own a Weider Pro 4300, and am looking to get muscle back in arms, legs, and torso at a steady pace. Any good workouts? Thanks in advance!
