@ppat4u OTF is mostly cardio with some light lifting while CF is 50/50 mix of cardio and lifting. Both are forms of HIIT and both require you to follow a nutrition program to get your full results. No way around it except for genetics.
@ilovejesus56129 I was eligible for the masters 55+ division for the first time this year which is equivalent of the scaled version. I love it because scaled is always a better workout for most normal folks.
