Todd Carmichael, co-founder of coffee roaster La Colombe Torrefaction, trains intensely to prepare for extreme adventures like trekking across Antarctica. His training includes metabolic circuits that blast every muscle group to failure without rest for 30 minutes. He also does intense cardio like 14-hour weighted StairMaster sessions. Carmichael advises getting the body used to intense exertion and allowing for ample recovery time. During expeditions, he finds relief in simple pleasures like sipping coffee for 15 minutes and packing treats like sausage and chocolate. Carmichael also stays in shape by taking spinning classes with his wife.
