A lot of research shows great benefits can come from shorter workouts (~25-35 minutes total) with alternating periods of high intensity and recovery. So should we stop doing “traditional” runs, bike rides, swims and other cardio sessions, and just do high-intensity interval training (HITT)?
Based on my own experience, a review of what experts are saying, and some simple logic about “why we exercise,” I think the answer is to seek the best of both worlds here.
Incorporate some HIIT benefits into your routine, but do also retain some longer, moderate cardio workouts. Here’s why, and some tips for getting started.
