Hi Jaime,
So happy you're here! Most of the TSS app doesn't have cardio - the only classes with cardio are 30min dance cardio, quickie dance cardio and some Full Bodies ( although only 1-2 songs that you can easily skip) -- the rest are all low impact sculpt. Like everyone else said, there are quickie full bodies and Full bodies without cardio, but those with cardio you can always fasts-forward through since there are only 1-2 songs. 30min Sculpt would be a great class for you to try and the quickie full bodies with no cardio.
