Lunge & Pallof Press | Isometric Hold | Core | Hamstring Rehab

This one is awesome for hip strength, core strength, balance, breathing, and mental focus. Since we are performing an isometric lower body activity, the goal is to ground your entire foot into the floor, squeeze your bum, and ensure your knee is tracking over your foot (not inside, nor massively outside your foot).
Keep your shoulders stacked over your hips.
Your feet should be wide, keeping your squat width (not directly behind the other).
Perform reps to fatigue, 3 sets on each leg.
