If the biggest challenge of doing 200 consecutive crunches is keeping track of the count, here’s a tip: Britney’s song 3 starts with the lyrics: one, two three. That gets you almost half-way to seven. Steps’ 5-6-7-8 gets you with few omissions past that and most of the way to 10, and SClub7’s Two in a million name drops a couple extra numbers. You’re welcome!
