This workout uses barbell, weight plate and bodyweight exercises to blast all major muscle groups. LES MILLS GRIT Strength takes cutting-edge HIIT and combines it with powerful music and inspirational coaches who will be down on the floor with you, motivating you to go harder to get fit, fast.

LES MILLS GRIT is scientifically-designed to shift your fitness to the next level. The HIIT effect means you increase aerobic fitness, unleash fast-twitch muscle fibers and grow lean muscle tissue, burning fat. But don’t take our word for it. See findings from the Les Mills Lab for more evidence.
