Four rounds for time
run 500 m
rest 90 seconds
**aim for a two minute or less time on each round
I changed up this work out a bit so there was no rest period. Each round I ran (lightly) for the 400m, but then tried to sprint for the last 100m. In between each round, I did 20 sit ups. Today was my kind of work out! I always enjoy the cardio, but struggle when it comes to weights.
