Curling your palm to face back toward your head while pressing one dumbbell changes the arc toward the upper chest and keeps the elbow close to your side. Underhand plus single-arm is a rare pairing, with the offset load twisting you while the grip alters the path, so keep it light and deliberate, mostly as a change of stimulus.

How to do the Reverse Grip Single Arm Dumbbell Bench Press

  1. Sit on a flat bench with a dumbbell in one hand, palm facing towards your body.
  2. Place your feet flat on the ground and keep your back straight.
  3. Raise the dumbbell to shoulder height, keeping your elbow close to your body.
  4. Press the dumbbell upwards until your arm is fully extended.
  5. Pause for a moment at the top, then slowly lower the dumbbell back to the starting position.
  6. Repeat for the desired number of repetitions, then switch to the other arm.

Tip: Squeeze the bar hard and keep the wrists straight over the elbows through the whole rep.

Muscles worked

Primary

Pectorals · Chest

The chest presses the arms together and forward, and decline and wide grip variations put more emphasis on the lower and outer pecs.

Secondary

  • Triceps — The triceps lock out the elbow on every press and dominate close grip and skull press variations.
  • Delts — The front delts assist every press and take over on Bradford and behind the neck variations.

Common mistakes

  • Elbows flaring wide — on horizontal presses keep the elbows at roughly 45 degrees from the torso; pressing overhead, keep them under the weight instead.
  • Losing the shoulder blade position — on bench-style presses set the shoulder blades back and down and keep them there; overhead, let the shoulder blades rotate up naturally with the arms.
  • Bouncing or rushing the bottom — control the bar down and pause for a beat before driving up, especially on decline and close grip variations.
  • Not committing to a variation — Bradford presses, skull presses and the like are hybrids; pick a fixed range and stick with it for the whole set.

Where it fits in a workout

Presses are the main movement in a push session and should go first or second. Superset them with a row or pulldown for a push and pull pair.

When to talk to someone

  • Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
  • Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
  • Pregnant: ask your obstetric care provider which exercise suits you.
