Kalsu
Originally "Kalsu" comes from CF Football, we used its protocol but replaced the heavy thrusters with Kettlebell swings.
In a minute perform 5 burpees then for the remainer of the minute perform kettlebell swings until the minute has elapsed, then another five burpees in this pattern until 100 swings have been performed.
