Description

An exercise that primarily targets the lower abs and obliques while lying on your stomach with your hands under your head, performing a flutter kick movement with your feet.

How to Do Reverse Flutter Kick on Floor (hand under head)

1
Setup
Lie face down (prone) on the floor with your legs extended straight behind you. Place your hands under your head or forehead for comfortable support.
2
Setup
Engage your core muscles slightly by drawing your navel towards your spine to stabilize your pelvis and protect your lower back.
3
Gently lift both legs a few inches off the floor, keeping your knees mostly straight but not locked, to find your starting position.
4
Begin performing small, controlled alternating kicks, moving one leg slightly higher as the other lowers in a continuous 'flutter' motion.
5
Maintain a consistent and controlled pace throughout the movement, focusing on squeezing your glutes and hamstrings with each kick. Breathe naturally.
6
Continue the flutter motion for your desired duration or repetitions, then slowly lower your legs back to the floor with control.

Tips

Focus on glute and hamstring activation: Consciously squeeze your glutes and hamstrings as you lift each leg to maximize muscle engagement and prevent lower back strain.
Maintain a stable torso: Keep your core engaged and avoid rocking your hips or torso excessively during the kicks; the movement should primarily come from your hip joints.
Control the range of motion: Perform small, controlled movements rather than large, forceful kicks, as a smaller range of motion better isolates the target muscles and reduces lower back stress.
Breathe smoothly: Don't hold your breath; inhale and exhale in a controlled manner throughout the exercise to maintain oxygen flow and core stability.

Common Mistakes

×Arching the lower back excessively can happen if the core isn't engaged; fix this by actively pulling your navel towards your spine and keeping your pelvis stable.
×Using momentum instead of muscle control, indicated by jerking your legs up and down, reduces muscle activation; fix this by slowing down the movement and focusing on a consistent, deliberate flutter.
×Lifting the legs too high can strain your lower back; fix this by keeping the legs only a few inches off the floor and concentrating on glute contraction rather than height.
