Need a chest and back routine
What are your goals, get leaner, gain muscle...etc?
Chest flies, push ups, wall push ups, dumbbell chest press, try and incorporate the stability ball. As far as back goes, ez bar bent over rows, dumbbell bent over rows, farmers pull, cable rows...and if you are trying to drop body fat instead of counting reps go by seconds. Ex. 3 sets of 20 seconds...
