The best total body workout
If there's one workout I always come back to, it's this one: The 5x5x5. If I don't have a lot of time or I just don't feel like doing anything (which is often), this is it. It checks every box:
Conditioning (cardio and intervals)
All you need are 2 (heavier) dumbbells and a watch or phone to time your 1 minute recovery.
Complete all 5 moves in a row without setting the dumbbells down to rest. If you stay honest with the 1 minute recovery, this workout should only take you 15-20 minutes.
