Movement Breakdown
Ruck Flutter Kicks
- Lie on your back with the ruck resting on your lower shins or held at your chest.
- Lift your legs a few inches off the ground and flutter them in a small, steady kicking motion.
- Keep your lower back pressed into the ground throughout.
Ruck Push-ups
- Begin in a plank position with your hands on the ground and the ruck on your back.
- Hands slightly wider than shoulder-width, body forms a straight line from head to heels.
- Lower your body by bending your elbows, keeping them close to your body.
- Once your chest touches the ground, push back up to full extension.
Ruck Russian Twists
- Sit with knees bent, heels on the ground, torso leaned back slightly, holding the ruck at your chest.
- Rotate your torso to tap the ruck on the ground beside your hip.
- Rotate to the opposite side and repeat, keeping your core engaged throughout.
Ruck Shoulder Taps
- Start in a plank position with the ruck on your back, hands under your shoulders.
- Keeping your hips square, lift one hand and tap the opposite shoulder.
- Return your hand to the ground and repeat on the other side.
- Keep your core braced so your hips don't rock side to side.
