The 90 degree pushup is an advanced calisthenics move that combines a handstand and a bent-arm planche.

• Start in a stable handstand position, either on the floor or parallettes.
• Slowly lower your body while simultaneously leaning your shoulders forward. Your goal is to keep your body straight as it moves from vertical to horizontal.
• Once you reach the bottom position (the bent-arm planche where your body is parallel to the ground and elbows are at a 90-degree angle), pause briefly.
• Push back up by driving your shoulders back and extending your arms, returning to the handstand position.
• Maintain full body tension and a hollow body position throughout the entire movement.
