Using dumbbells will work more muscles around the shoulders and chest than using a barbell because they're forced to keep the weights stable, and it's well worth developing those muscles before moving on to heavier barbells. Lie on a flat workout bench with your feet flat on the floor.
The leg press is a weight training exercise in which the individual pushes a weight or resistance away from them using their legs. The term leg press also refers to the apparatus used to perform this exercise.
The bench press is an upper-body weight training exercise in which the trainee presses a weight upwards while lying on a weight training bench. The exercise uses the pectoralis major, the anterior deltoids, and the triceps, among other stabilizing muscles. A barbell is generally used to hold the weight, but a pair of dumbbells can also be used.
A power rack is a weight training equipment that functions as a mechanical spotter for free weight barbell exercises without the movement restrictions imposed by equipment such as the Smith machine.
