Introduction
The "Machine Kickback" exercise primarily targets the hamstrings and glutes. It is beneficial in strengthening these muscle groups, improving lower body flexibility, and enhancing range of motion during walking and running. This exercise is particularly effective for individuals aiming to build lower body strength, correct muscular imbalances, or prevent injuries associated with sports activities that involve a lot of leg movement.
Muscles Worked
- Primary: Quadriceps (especially the rectus femoris)
- Secondary: Hamstrings, glutes, and calves
How to Do It (Step-by-Step)
- Stand firmly on the floor with both feet shoulder-width apart, facing a machine.
- Quickly and forcefully pull the handle or bar of the machine towards your body while simultaneously pushing against it with your other foot.
- Ensure your grip is secure and maintain balance during the movement. Tip: Keep your back straight and core engaged to minimize strain and increase effectiveness.
Rep & Rest Guidelines
- Machine Kickback (Strength): 4–6 reps, 2–3 min rest
- Machine Kickback (Hypertrophy): 8–12 reps, 60–90 sec rest
- Machine Kickback (Endurance): 12–20 reps, 30–60 sec rest

Workout History can help you track your progress and optimize your workouts over time.
A machine kickback is caused when the workpiece becomes jammed or bound in a sudden, violent manner due to improper setup, operation, or feed rate.
Preventive measures include proper clamping, using sharp tools, maintaining appropriate feed rates, and ensuring the machine is properly set up and calibrated.
Stop the machine immediately. Assess any damage, unjam the workpiece, and then carefully reevaluate your setup before continuing.
Yes, a machine kickback can result in injuries to operators or damage to equipment due to the sudden, violent movement of the workpiece.
Always wear appropriate personal protective equipment (PPE), read and understand the machine operator's manual, and follow all safety guidelines provided by the manufacturer.
