Primary muscles are Glutes, Quadriceps, Claves, Anterior Tibs, Core, and Upper Back. This video aims for the MTNTOUGH Athlete to analyze their movement under axial loads biomechanically. Record this exercise from the front, rear, and side planes to maximize your levers under a load. To decrease energy expenditure, it is essential that you have baseline strength in the Squat (1.5x BWT) and Deadlift (2.0x BWT) and be efficient in changing your gates based on the terrain. The three gates are Glute dominant for going up grades(elongated stride heel to heel, slowed tempo), Quad dominant, or quick tempo for traveling on flat ground or going downgrade (mid-foot with a faster tempo). Lastly, shuffle is when you need to move quickly based on the situation, boot top high run (maintain for short distances, prefer flat ground and increased tempo). Apply the appropriate exercise prescription to turn your weakness into strength if you find a deficiency.
