I'm practicing hip-hop abdominal muscles, but I'm just getting started. A * * * has five episodes, so you need to repeatedly choose which of these five episodes is the next day according to the curriculum. It should work. Exercise abdominal strength and sweat a lot. I don't know much about T25. However, hiphop's coach also has a more bodybuilding and weight-loss exercise-insanity, which will last for 63 days. I will stop using it in two weeks, but the effect is already obvious.
