Exercise Notes
The wall squat isohold serves as a fundamental quadriceps endurance exercise. You can perform it anywhere you find a wall. Keep perfect posture throughout the duration of the set by keeping the chest up and sitting tall. Add variety to this exercise by changing the hip angle during the set. For example, start at a more difficult hip angle that places your hips lower than your knees, then move to a thigh-parallel position as the set gets challenging, and finally moving to a hips-higher-than-knees position.
