A full functional workout woven between the runs — alternating snatches, walking lunges, devil press, overhead carries, kettlebell deadlifts, burpee broad jumps, slamball ground-to-overhead, Zercher carries and slamball sit-ups. Every station is designed to test strength, engine and grit in equal measure.
