What you'll gain

• Increases upper chest and biceps involvement compared with a pronated grip on the same flat bench.

• Gives a fresh pressing stimulus for lifters with no access to an adjustable incline bench.

• Alters the wrist and shoulder position, which some lifters find kinder on a sore shoulder.

Step-by-Step Instructions

1. 1

   Set the rack height on a flat bench and load the bar conservatively for your first sets.

2. 2

   Lie back with your feet planted and take the bar with an underhand grip a little wider than shoulder width.

3. 3

   Set your shoulder blades into the bench, then unrack the bar with a spotter's help.

4. 4

   Lower the bar slowly to your mid-chest, keeping your wrists stacked over your forearms.

5. 5

   Pause without letting the bar rest on your chest, then press it back up.

6. 6

   Stop short of locking the elbows and keep your glutes and shoulder blades on the bench throughout.

Common Mistakes

• Unracking a supinated bar without a spotter risks losing it backward before the first rep is under control.

• Letting the wrists bend back under load puts the bar behind the forearm and strains the wrist joint.

• Loading it like a standard bench press overwhelms an unfamiliar grip and forces the form to break down.

• Lifting the feet or hips off the bench to grind a rep removes the stable base the press depends on.

About This Exercise

The reverse-grip barbell bench press keeps the flat bench setup but supinates the hands so the palms face the head. That rotation changes which fibers work: bench press EMG shows a supinated grip increases activity in the clavicular portion of the pectoralis major and in the biceps brachii compared with a pronated grip. The triceps still extend the elbows. The grip is the risk. Unracking and re-racking a supinated bar is awkward and the wrists sit in a less familiar position, so a spotter and conservative loading are sensible. As an asset it is the upper-chest alternative for lifters restricted to a flat bench, useful in barbell filters, grip-variation content and builders that rotate pressing stimulus without changing bench angle.
