Chains Mode on Tonal simulates the classic training technique of lifting with physical chains. As you move through an exercise, Tonal dynamically increases resistance during the concentric (lifting) phase, mimicking the feel of more chain links lifting off the floor. You’ll feel the challenge rise as your power builds, then taper as you lower the weight. Used in moves like deadlifts, squats, and performance training, Chains Mode helps develop your strength, speed, and explosiveness. | Tonal
