6. Dips
How to do it: Place both hands on the edge of sturdy support, like a bench, to support your body weight while keeping your arms straight. With your feet on the ground, keep your knees bent at a 90° angle as if you were sitting on air. Bring your body close to the ground by bending your arms until your elbows form a 90° angle. Then, bring your body back up until your arms are straight.
If you want to make this exercise harder and get even better results, you can use parallel bars. Keep your feet off the floor, hold the bars tightly with your hands, and keep your arms close to your body. Lower your body between the bars, then lift it back up while your feet are in the air.
