WALL SIT

TIPS: Focus on always having your weight on the entire soles of your feet. Your head and chest should always look forward.
STARTING POSITION:
Find a stable wall and stand straight with this wall behind you. Spread your feet at shoulder width apart and put your toes slightly outwards. Contract your pelvic floor and core while keeping your chest up. Place your hands behind your neck.
MOVEMENT:
Bend the knees and move your glutes backwards, lowering your legs until your thighs are parallel to the floor and your back is resting on the wall. Press your head, upper back, and hips against the wall. Hold the position during the required time. Make sure your knees are always pointing towards the toes and they are at 90º.
