Description
This exercise targets the pectoral muscles by pressing dumbbells in an alternative manner from a high starting position while laying on a bench.
How to Do Dumbbell Alternate Bench Press (high start)
- 1Setup
Lie supine on a flat bench with your feet flat on the floor, shoulder-width apart, and a dumbbell in each hand, palms facing forward.
- 2Setup
Press both dumbbells straight up over your chest until your elbows are fully extended, ensuring the dumbbells are directly above your shoulders.
- 3
Slowly lower one dumbbell towards the side of your chest, maintaining control and keeping your elbow slightly tucked (about 45 degrees relative to your torso).
- 4
Once the dumbbell reaches chest level, powerfully press it back up to the starting position above your shoulder, contracting your pectoral muscle.
- 5
Immediately repeat the lowering and pressing motion with the opposite arm, maintaining the extended position with the non-working arm throughout the set.
Tips
- Maintain constant tension on the non-working arm by keeping the dumbbell pressed overhead; this enhances stability and increases time under tension for that side.
- Focus on controlled eccentric (lowering) movement for each repetition, taking 2-3 seconds to lower the dumbbell to maximize muscle fiber recruitment.
- Keep your shoulder blades retracted and depressed throughout the exercise to provide a stable base for your pressing motion and protect your shoulders.
- Engage your core by bracing your abdominal muscles to prevent your lower back from arching excessively off the bench during the presses.
Common Mistakes
- ×Allowing the non-working arm to drop or lose tension reduces the stability and overall effectiveness of the exercise; keep the non-working dumbbell locked out overhead.
- ×Flaring your elbows out too wide places unnecessary stress on the shoulder joints; keep your elbows at approximately a 45-degree angle to your torso as you lower the weight.
- ×Bouncing the dumbbells off your chest or using momentum to press them up diminishes muscle engagement; ensure a controlled lower and a deliberate press using only muscle power.
