Back & Glutes Challenge
This four-week challenge from Katie Martin focuses on strengthening and toning your posterior chain - that’s the muscles down the back side of your body such as your glutes, hamstrings, back and calves. Perfect for intermediate fitness levels, this gym-based program can also help to improve your posture, balance, agility and overall athletic performance.
