These are NO JOKE.. My trainer sculpted my arms doing these here! Spider-Man Press-Up. Targets: Chest, Triceps, Abs, Obliques, Butt, Hips. Start in Push-up position, bring knee out to side to elbow, press up and return to start. Do 8 reps. Switch sides and repeat. Do 2 sets.
All you need to do is increase by 10 every 3 days .. You will really feel your ass the next day !!! AMAZING. Running doesn't do anything for your butt, just makes you more aware of the fact that it's wobbly!!!!
