Hannah demonstrates Evil Jumps TECHNIQUE: This move requires good squat and lunge form. It is important to keep hips square throughout the entirety of the movement and to resist the urge to twist when landing in the lunge position. Keep core engaged the entire time. ADVANTAGES: This is a great way to incorporate some conditioning into your workout. They're called evil jumps for a reason as they can be very tiring but they are a great workout to include in any leg workout. FAULTS: Some of the most common faults include twisting and sinking into the back leg on the lunges. It is important to maintain good squat form for the whole movement SCALING: This can be broken down into squats and alternating lunges without the jumping portion.
