Extension and flexion of one leg and arm in supine position alternating ► dead bug

Individual work

Lie on your back, arms in front of your chest (pointing upwards), legs bent and held high (approximately 90 degrees at the knee joint, thighs pointing upwards, lower legs parallel to the floor). Extend one arm and one leg crosswise in extension of the body (without lowering them to the floor), then return the leg and arm to the starting position. Switch sides after each exercise.

Attention:
Never lower your extremities completely; your lower back should always be in contact with the floor (no hollow back, consciously tense your stomach).

Lighten:
Lower your arm and leg less.

Harden:
Additional weight for the arms/legs.

2-4 weight cuffs/2 weight balls/dumbbells ► Make the exercise more difficult (additional weight)
