Hey about the Self Defense Training Camp game you made a guide for you said only Blazing Reflexes would glitch. I just 5 starred everything and both Expert in self defense as Blazing Reflexes glitched on me. So there are two glitched achievements.
Also I wouldn't rate the cardio part easy. Because of the awful clap and front knee raise combi punch tracking it's hard to 5 star those. I actually had most trouble with cardio 2 and 3 which are rated easy. And I do work out a lot so I'd suggest to tweak that a little. I also double checked all my stars and everything is 5 star + I got those 5 star/max rank achievements.
