Knee injuries are very common in MMA sports. Athletes need to ensure there is sufficient work to strength the knee in their program to safeguard against this.
Hindu Squats using the 8cm Squat Bricks are a great way to strengthen the knee by placing it at end range knee flexion. By keeping this upright posture the Hindu Squat allows us to isolate the quads through knee extension. The Hindu squat is also great exercise to improve hip mobility by allowing the athlete to get to a far lower squat position than they can achieve without elevation. Often times athletes will comment how they can really feel the outside of the glutes working (hip external rotation) vs when they perform squats without elevated.
Remember hip strength is also of the upmost importance so the same amount of hip strength work should accompany the Hindu Squat. Try super setting 4 x 8 Reps of an RDL (Glute/Hamstring) with 10 x 10 Reps of a Bodyweight Hindu Squat
