This compound movement bridges core stability and lower-body power by combining a sit-up with a functional squat-to-stand transition. It effectively builds explosive strength in the glutes and quads while demanding high levels of abdominal control.

Setup
- Sit on the floor or a low step with your knees bent at a 90-degree angle and feet flat on the ground.
- Lower your torso back until your shoulder blades touch the floor, keeping your core engaged.
- Extend your arms straight out in front of you to help shift your center of mass forward during the transition.
How to do it
- Perform an explosive sit-up by driving your torso forward and reaching your arms toward your toes.
- As your weight shifts over your mid-foot, plant your heels firmly and drive upward into a standing position.
- Exhale forcefully as you stand up, then inhale as you hinge at the hips to sit back down with control.
- Lower yourself back to the starting supine position slowly to maximize time under tension on the abs.
Form checklist
- Keep your heels glued to the floor; do not let them lift as you transition to standing.
- Maintain a neutral spine and avoid excessive rounding of the lower back during the sit-up.
- Ensure your knees track in line with your toes and do not cave inward during the stand-up phase.
- Control the descent back to the floor rather than 'flopping' down.
Pro tips
- Think of the movement as one fluid motion; the momentum from the sit-up should carry directly into the drive of the squat.
- To increase core recruitment, keep your arms crossed over your chest to remove the assistance of arm momentum.
Make it harder
- Hold a light kettlebell or dumbbell at chest height in a goblet position throughout the entire movement.
- Perform the stand-up phase on a single leg to significantly increase the balance and unilateral strength demand.
Frequently asked
- What muscles does the sit-up stand-up work?
- The sit-up stand-up primarily targets the abs, deltoids, pectorals, and triceps, and also works the erector spinae, obliques, and serratus anterior as secondary muscles.
- What equipment do you need for the sit-up stand-up?
- The sit-up stand-up requires no equipment — just your body weight.
- Is the sit-up stand-up good for beginners?
- The sit-up stand-up is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
