6 Strength Training Moves You Can Do with a Park Bench
No gym membership, no problem: All you need is a simple park bench to get great arms, abs, and legs -- aka the perfect bikini body for summer -- fast
Step 1: Sit on the edge of the bench with your hands next to you for balance. Lean back slightly and lift your legs off the floor (keeping your knees straight) until your torso and legs form a "V."
Step 2: Bring your legs into a crunch by bending your knees, then straighten your legs back out. Do three sets of eight crunches.
Challenge yourself: After a set with your knees together, do one set of 18 crunches alternating bending your left and right legs, keeping the other extended. Finish with a final set of eight crunches with your knees together.
