Concurrent Cardio (HIIT)
Performing high intensity interval training (HIIT) concurrently with resistance training does not negatively impact hypertrophy or upper body strength*. We recommend performing HIIT after resistance training.
If choosing medium intensity cardio, it is likely prudent to perform this on a separate day from your resistance training for ≤30 min per session.
*Sub analyses showed a trend for lower body strength to be negatively affected by cycling HIIT, but not sprinting.
