Assault Bike Run
- Intermediate
- Compound
- Timed hold
- Upper arms

Muscles worked
Setup
- Stand with your feet shoulder-width apart and your toes pointing slightly outward.
- Engage your core and keep your chest upright with your gaze forward.
- Bend your elbows to 90 degrees, holding your hands in loose fists near your ribs as if gripping handles.
How to do it
- Lower your hips into a shallow squat position to load your glutes and quadriceps.
- Explosively drive one knee toward your chest while simultaneously punching the opposite arm forward and pulling the other elbow back.
- Immediately switch sides in a fluid, alternating 'running' motion while maintaining a slight squat depth throughout.
- Breathe rhythmically, exhaling sharply with every knee drive to maintain high intensity and core stability.
Form checklist
- Keep your spine neutral and avoid rounding your shoulders forward during the arm drive.
- Land softly on the balls of your feet to minimize joint impact.
- Ensure your knees stay aligned with your toes and do not cave inward during the squat phase.
- Maintain a high, consistent cadence while keeping your chest lifted.
Pro tips
- Focus on a powerful 'push-pull' arm action; imagine you are moving through water to maximize lat and pectoral activation.
- Keep your core braced throughout the movement to transfer power efficiently between your upper and lower body.
Make it harder
- Increase the depth of the squat between each stride to increase the demand on the glutes and quads.
- Hold light dumbbells or weighted gloves to significantly increase the resistance for the deltoids and arms.
