Don’t have access to a gym? Here’s a way to target the arm muscles without weights.
To start, sit with your hands on the floor just behind your hips. Place your feet in front of you with knees bent. Keep your chest open and stomach pulled flat. (Beginners can keep hands facing front toward the toes and feet flat and on the floor.) Pull in, and lift the hips off the floor, stretching the elbows. Bend the elbows slightly and straighten.
Repeat 30 times.
