Place a Barbell at Shoulder height in a Power Cage or Squat Rack.
Make sure the setup is sturdy enough to handle your bodyweight.
Hold the barbell with a slightly wider than shoulder-width overhand grip.
Hang from the bar
Place your feet on a bench in front of you. The higher the bench, the easier the pull-up movement.
Keep the legs straight and close to each other.
Breathe in and tighten up the entire body.
Start by pulling your shoulder blades down and back.
Continue till the chin crosses over the bar.
Keep elbows close to your body.
Lower body down with control.
Exhale and repeat.
