100 Thrusters for time/load. *5 Burpees at the start of each minute. *20 minute time cap. Note: This workout is based off a hero workout called “Kalsu” where the load is prescribed at 135/95lbs. As a guide, I would recommend a load that you can do around 15 UB reps to make this a survivable experience! Chris. Photo: Thanks to Tom_Bennet_Photo.
