Triceps and Calves .. how to do exercise at home

1. Triceps

Bench Dips

These can be done on the edge of a chair or bench. Sit on the side edge of a flat bench or the front edge of a chair. Place your hands on the edge of the chair right beside your glutes and grip the edge. To start with, your feet should be flat on the floor about two feet in front of you with your knees bent. Move yourself off the chair so you are now supporting yourself on your hands. Bend your arms, dipping your body down. Go down only as far as you feel comfortable, being careful not to bounce out of the bottom. Push back up, squeezing the triceps. It is important to keep your back close to the edge of the bench as you do these to minimize shoulder stress. When you're done the set, push yourself back onto the chair.

2. Calves

Standing Calf Raises

This exercise can be done on the edges of stairs, wood blocks, books, etc. Do both legs at the same time to start with then, as you get stronger, do them one leg at a time. Hold a bag in your hand for resistance as you get stronger Stand on the edge of the block with only the balls of your feet on the block. Keeping knees stiff and bending only at the ankles, lower your heels down towards the floor. Go down until you feel a strong stretch in your calves. Reverse the direction without bouncing and push up as high as you can. Do this movement slowly to feel the contraction all the way up.
