Use this exercise to build amazing quadriceps! Word of advice: The higher the box, the more quad engagement you will experience.

Main Muscles: Quadriceps, Hamstrings, Gluteus Maximus

Key Points:

– Keep your chest up, back arched and core tight

– Begin standing with both feet on the box, so that you can lunge off of it onto the floor

– Lunge so that your back knee lines up with your leading heel

– Keeping your bodyweight on your leading heel and your back arched, take your chest towards your thigh until you feel your quadriceps engage

– Push your heel through the floor to drive yourself back on to the box

– Train both sides evenly
