Tried something new today. Did the HIIT thing on my cardio day.
Warmed up 5 minutes. Then went as hard as I could for 30 seconds, then back to normal for 30 seconds. I did that 5 times. Finished up with a 5 minute cool down for a total of 15 minutes.
I was honestly beat after that.
I’m gonna try this out for a while and see how it goes.
