Ragnarok is a strength workout that takes the body through slow, deep moves, executed in perfect form to slowly but steadily load the muscles so that they begin to feel the need to adapt. This is a deceptive-looking workout where the exercises themselves look easy enough. There is some emphasis given to the core as well as the four abdominal muscle groups. Hips and glutes are not overlooked and the lower body is also given a good workout. The trick here is to slow things down, rather than speed them up (and that includes the side kicks) adding to the fatigue factor.
Extra Credit: keep legs up after flutter kicks.
