Single-Arm Push-Up

What it is

This is a challenging bodyweight movement that builds significant upper body strength. It primarily works your chest muscles, with strong secondary engagement of your shoulders and triceps. You will perform this exercise by supporting your body weight on a single arm, lowering and pushing yourself back up.

Technique tips

• Keep your working hand directly under your shoulder.
• Widen your foot stance for better balance and stability.
• Place your free hand behind your back to maintain focus.
• Lower your body slowly, touching the ground gently.
• Maintain a straight line from your head to your heels.
• Control the upward phase by pushing through your palm.

How to track your progress

Log reps, and add the extra load if you wear a belt or a vest. Straddly counts your bodyweight in the estimated max, so added weight and extra reps both show up as progress, and new records are flagged during the session.
