How to do the 10-20-30 workout
- Warm up for 5 minutes.
- Go easy for 30 seconds.
- Go moderate for 20 seconds.
- Go fast for 10 seconds.
- Repeat steps 2 to 4 five times. That is one 5-minute set.

What the study found
In a 6-week study, runners who did 10-20-30 intervals twice a week at about 80% of max effort cut their 5K time by 42 seconds on average. Both effort groups raised VO2 max by 7% (Runner’s World).
No room to run? Use a jump rope
Swap running for jump rope: slow bounces for 30 seconds, steady skipping for 20, fast skipping for 10. A digital jump rope counts every jump, so you see progress week to week. Not a runner? Try Japanese walking, the same idea at walking pace.
