For interval training, it would be helpful to have a reps x seconds option when making unique exercises. For some reason, I'm having trouble using the progression spreadsheet to program various conditioning/interval training progressions. So far, the only solution I've come up with is to treat the conditioning exercise like a strength exercise (reps x weight), but to clarify in the notes that the weight is in seconds, which might lead some clients astray. The only way I can edit the progression spreadsheet to adjust the amount of reps and the number of seconds between intervals is to copy and paste the entire session. basketball stars
