The Kick Out Sit is a targeted isolation upper legs movement designed to train the Hamstrings with direct engagement of the Glutes.
Controlled plane of motion engaging target synergist muscle groups. Focus on deliberate eccentric control (2-3s) and active range of motion. Executing this with strict form maximizes muscle fiber recruitment while protecting joint structures.
Quick Exercise Facts
Target Muscle Activation
This move works the front of the hip and quads through a controlled leg extension from a seated position, which makes it useful for building hip flexor and quad endurance without any real load on the spine. It's a simpler, lower-impact way to hit the same muscles a leg raise trains, useful for people easing back into ab and hip work.
How to Do the Kick Out Sit
- Sit on the edge of a bench or chair with your feet flat on the ground and your knees bent at a 90-degree angle.
- Lean back slightly and place your hands on the edge of the bench or chair for support.
- Using your hamstrings, lift your feet off the ground and extend your legs straight out in front of you.
- Pause briefly at the top, then slowly bend your knees and bring your feet back toward your body.
- Perform for your targeted rep count, focusing on a deliberate tempo and maximum tension in the hamstrings.

Biomechanical & Joint Load Cues
Controlled plane of motion engaging target synergist muscle groups. Focus on deliberate eccentric control (2-3s) and active range of motion.
Common Mechanical Mistakes & Form Errors to Avoid
- Uncontrolled Lifting Tempo: Rushing through reps without establishing mind-muscle connection or eccentric control reduces muscle fiber tension.
- Spine Hyperextension: Compensating for limited joint range of motion by arching the lower back risks spinal facet strain.
- Unstable Foot Base: Poor foot position causing balance loss during movement execution creates energy leaks and injury risk.
Proper Breathing Patterns & Core Engagement
Inhale during eccentric lowering phase; exhale during concentric work phase.

Injury Modification & Joint Safety
Stop immediately if movement causes sharp joint or tendon pain; substitute with a joint-friendly variant. If joint irritation persists, immediately stop and substitute this movement with another exercise from the Upper Legs exercises category.
Muscles Worked
The Kick Out Sit primarily targets the Hamstrings, with Quadriceps as the primary synergist muscle group, along with the Glutes.

FAQ
- What muscles does the Kick Out Sit work?
- The Kick Out Sit primarily targets the hamstrings as the primary agonist. Synergist assistance is provided by the quadriceps along with the glutes. Maintaining strict biomechanical alignment ensures maximal tension remains focused on the intended muscle fibers rather than shifting to surrounding stabilizer joints.
- What equipment do I need for the Kick Out Sit?
- The Kick Out Sit is performed using no equipment — just body weight. Ensure all equipment is securely positioned with collars or safety pins locked before loading working sets. If you train in a home gym or minimal setup, explore our equipment-free and resistance band alternatives below.
- What is the most common form mistake on the Kick Out Sit?
- The most frequent error is uncontrolled lifting tempo: Rushing through reps without establishing mind-muscle connection or eccentric control reduces muscle fiber tension.. Controlling the 2 to 3-second eccentric lowering phase ensures maximal hypertrophic stimulus while shielding connective tissue.
- How many sets and reps should I perform on the Kick Out Sit?
- For muscle growth and density, execute 3 to 4 working sets of 10 to 15 controlled repetitions with 60 seconds rest, emphasizing a deep stretch and deliberate peak contraction on every rep.
- What's a good alternative to the Kick Out Sit?
- If you don't have access to the space or setup it needs, the Barbell Good Morning targets the same hamstrings using barbell instead. This alternative replicates the same joint angle and movement plane while allowing you to train effectively with different available gear.
