A short but hard interval workout, easily able to fit into an hour-long workout. You won’t be able to recover between sets. Go for 3 repeats and leave it at that. Don’t do it twice in a week or on back to back days.
- Warm up for 10 minutes
- Jump to 9 out of 10 effort for 3 minutes
- Rest for 2 minutes at 4 out of 10 effort
