Squat Mobility Complex
- Intermediate
- Compound
- Timed hold
- Lower legs
- Upper legs
- Waist
This dynamic flow improves hip, ankle, and thoracic spine mobility by combining a deep squat with rotational reaches and hamstring stretches. It effectively primes the glutes and hamstrings while activating the trapezius through overhead extension and thoracic rotation.

Setup
- Stand with your feet slightly wider than shoulder-width apart, toes turned out 15-30 degrees.
- Hinge at the hips and reach down to grab the tops of your feet or your toes with your hands.
- Engage your core and pull your shoulder blades down and back to set a neutral spine.
How to do it
- Pull your hips down into a deep squat, using your elbows to push your knees outward while keeping your chest upright and heels flat.
- Exhale and reach one arm toward the ceiling, rotating your chest toward that side to engage the traps and mid-back, then repeat on the other side.
- Inhale and lift your hips toward the ceiling into a hamstring stretch while maintaining your grip on your toes.
- Move through the sequence at a slow, controlled tempo, spending 2-3 seconds in each phase of the movement.
Form checklist
- Keep your heels glued to the floor throughout the entire squatting phase.
- Maintain a 'proud chest' and avoid excessive rounding of the lower back at the bottom of the squat.
- Ensure your knees track in line with your toes and do not cave inward.
- Follow your reaching hand with your gaze to maximize thoracic spine rotation.
Pro tips
- At the bottom of the squat, gently shift your weight from side to side to 'pry' the hips open and increase ankle dorsiflexion.
- Focus on pushing the floor away with your stationary hand while reaching high to create maximum tension and engagement in the trapezius and rhomboids.
Make it harder
- Hold both arms in an overhead 'Y' position at the bottom of the squat for 5 seconds to increase postural demand.
- Perform the complex with a slow 5-second eccentric (lowering) phase to further challenge stability and control.
Frequently asked
- What muscles does the squat mobility complex work?
- The squat mobility complex primarily targets the calves, glutes, and hamstrings, and also works the abs, erector spinae, and obliques as secondary muscles.
- What equipment do you need for the squat mobility complex?
- The squat mobility complex requires no equipment — just your body weight.
- Is the squat mobility complex good for beginners?
- The squat mobility complex is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
