Tank Top is a strength workout that engages all upper body muscle groups and activates the core. This means the moves are slow and meticulous, the push ups are deep, the punches are deliberate and utilize a full body movement behind them. You will get in the sweat zone with this but it will not tax you aerobically. What it will do is make you feel strong afterwards and it will contribute to better muscle tone, increased physical performance and the sense that you are in control of your body.
