The staff of Ambition Athletics finds that most gyms lead their members to failure. It may seem like a harsh stance, but it inspires them to push themselves to give their members hands-on education and coaching rather than turning them loose in a sea of machines. Indeed, the key piece of equipment the fitness studio uses has no moving parts at all: it's the simple kettlebell, whose use in strength training dates back about as far as you'd expect by looking at what's essentially a lump of iron with a handle. Focusing on fitness for performance, trainers help members to take control of their own wellness during personal training and small-group classes, where they teach everyone to safely swing kettlebells, use suspension equipment, and charm ropes to climb themselves.
