Although some grading is required for most construction projects, the California Coastal Commission is concerned about unnecessary or excessive grading and its effects on the coastal environment. Various designs and construction techniques exist to lessen the extent and effects of grading.
The deadlift is a full-body strength exercise. It works your legs, glutes and lower and upper back muscles. To perform a deadlift, place a loaded barbell or hex bar on the floor in front of you. Squat down, grab the handles and pull the weight off the floor, finishing in a standing position with the weight at thigh level.
The hexagonal shape also reduces contact of the barbell with your shins when you lift the bar off the ground during the deadlift. The biomechanics of a hex bar deadlift are slightly different than of a straight barbell deadlift. The same primary muscles are worked during both, but the recruitment of each muscle is a bit different.
