Standing Cable Row Variation
Here are two variations on the cable row for back, depending on the angle of your body. Each works a different part of the back. Stand with one foot set on the seat for stability. In the first variation, lean forward at about 45 degrees, and row by reaching forward, then pulling the handles back to the side of your chest. For the second variation, you lean back at an angle of around 45 degrees, to work a different part of your back. Again, stretch forward, squeeze back. In both cases, keep your back straight, shoulders back at all times. Note that Obi is using separate handles, rather than a fixed handle - allowing him to twist and squeeze at the top of the movement.
