This is a very useful exercise to help build up your biceps and you can do it literally anywhere. You will need a resistance band which you place on the floor underneath your feet. You then grip the other end of the resistance band with your hands, standing fully upright, with the palms facing inwards. While ensuring that only your elbows move, simply “curl” the resistance band up toward your shoulders, pause and flex your biceps, and then lower back to the starting position. At all times you need to ensure there is significant tension on the resistance band to get the greatest benefits.
