For leap year’s extra day, we have a challenge that takes 6 minutes (or less) and burns extra hot. You must be warmed up to do this, so before you launch, do:

2 sun salutations with spiderman stretch
10 squats, 10 pushups
20 jumping jacks
10 squats, 10 pushups
2 sun salutations with spiderman stretch

Then:

3 double push-up triple tuck jump burpees
bear crawl 15-20 feet point A to point B
12 V-ups (if you have access to a pull up bar, do toes to bars or knee to elbows)
high knee skips point B to point A

3 rounds

The double push-up triple tuck jump burpee is a burpee with 2 push-ups rather than 1, and in place of that little bunny hop at the end, you’re launching yourself up into 3 tuck jumps where you land as softly as a ninja pow pow. If you are not able to land soft as a ninja, do the regular bunny hop.

At the end, stand up tall on your toes and reach your hands way up.  Feel that blood moving through you? That life, baby. Go get it.
