Add some spice to your leg day warm-up with Cossack squats (BONUS: on a BOSU! This dynamic move lights up your glutes, adductors, and hip flexors while dialing in balance and ankle stability. By moving laterally and loading one leg at a time, you’re prepping your body for deeper squats, stronger lunges, and smoother movement overall. Stability + mobility = better performance and fewer injuries. #strength #strengthening #functionalfitness #cossack #legday
