Lay flat on a bench with your feet on the ground. Place your hands on the barbell so that when the bar is at its lowest point your elbows are at 90 degree angles. Lower the barbell slowly and as low as possible. Push the bar back up keeping your back on the bench and feet still. This can also be done with dumbbells.
Do this exercise with the best exercise equipment. We recommend using a bluetooth chest strap heart rate monitor or a smartwatch for more training optimization & performance tracking.
