Workout Update: Lift 4/Shaun 20/645 Cardio hybrid: Day 40

On day 40, I did the "Ass and Abs" workout from Shaun 20 (which is the last workout in that program I had not yet done) and Legs (HIIT) from Lift 4 in the evening. The Shaun 20 workout is another circuit workout with two blocks that you repeat twice. You do need a moderate sized weight for some exercises. Each circuit has four exercises consisting of two leg exercises and two ab exercises. You do each exercise for one minute and get a break after you have done all three exercises and then between the two circuits. The Lift 4 workout was challenging even though, aside from triple bear, it did not have the most challenging HIIT moves in the programs.
