Prisoner High Knee Cardio
The prisoner high knee cardio is a bodyweight cardio exercise that combines the high knee drill with the prisoner arm position. Placing the hands behind the head eliminates arm momentum and increases core and upper body engagement while sustaining cardiovascular demand.
How to do it
- Stand upright and place both hands behind your head with your elbows pointing outward.
- Begin lifting your knees alternately toward your chest in a rapid high-knee jogging pattern.
- Keep your chest up and your elbows back throughout the movement.
- Pump your legs continuously at a brisk pace.
- Continue for the desired duration while maintaining the prisoner hand position.
Form cues
- Keep your chest proud and open.
- Interlock your fingers gently behind your head.
- Drive your knees upward toward your chest.
- Land softly on the balls of your feet.
- Maintain a steady, rhythmic breathing pattern.
Breathing: Inhale steadily through your nose and exhale rhythmically through your mouth as you drive your knees up.
Common mistakes
- Dropping your elbows forward, which rounds your upper back and reduces core engagement.
- Pulling on your neck with your hands, which can cause unnecessary cervical strain.
- Leaning back to lift your knees, which shifts the work away from your core and hip flexors.
- Stomping your feet loudly, which increases impact stress on your joints.
Muscles worked
