- Biathon rips! Jack your heart rate as high as it can go for extended aerobic skiing. Quick, now slow your heart rate down as quickly as possible and shoot a tiny target *in between* beats. Now get up and go as fast as you can. Repeat.
- biathlon rules so hard "go skiing and then pick up this gun and fire it" fantastic combo (and it actually works! the challenge of calming yourself down enough to be able to fire accurately is intense)
