The Fighter, as the name suggests, is a combat moves based coordination, strength and balance workout that tests tendon strength, muscle suppleness, core strength and balance in one, easy, flowing set of exercises. Focus on form, performing each exercise as fully as possible. Try holding each kick at full extension for a second before retracting the leg to kick again, it helps develop good balance and strong tendons. Swivel on the balls of your feet as you throw your punches so your bodyweight goes behind each punch you throw. Add EC if it all still feels too easy.
