Hi yes, they are a similar protcol but different workouts. TT is audio coaching though paired with remixes, so that's what makes it so special/different. You could easily sub TT for your cardio in MYB if you wanted to, I know many do! Hope this helps!
@Kinziger23 As part of MYB you do get cardio / treadmill runs as well as strength workouts however it does not include access to the TreadThrill site / membership and audio coaching which is specific to TreadThrill members. There is a free trial offer for TreadThrill if you are interested in trying it! Hope you like it! xo
