Grasp barbell with both hands with palms facing down. Use a shoulder width grip. Lean slightly forward to maximize front delt involvement. Start with the barbell in front of the thighs.
Raise the barbell with elbows locked to eye level. Lower the barbell slowly to starting position. Repeat.
Don’t rest the barbell on the front of the thighs. Bringing the barbell slightly past parallel helps involve the traps. This is an isolation exercise so do not use too heavy a weight that you have to use momentum to get it up. Feel the anterior delts do the work.
