20秒运动，10秒休息，共八组，这是让这个名字成名的方案 —— 但每一个环节都可灵活调整：运动时间、休息时间、组数、强度。让它更难，让它更长，让它完全属于你。无论你设置什么样的间隔，我都会精确到秒地为你把关 —— 这一点绝不妥协。
20 on, 10 off, eight rounds is the protocol that made the name — but every piece bends: the work, the rest, the number of rounds, the intensity. Make it harder, make it longer, make it your own. Whatever intervals you set, I hold them to the second — that part never bends.
