Frank Zane's Leg Blaster
Forged from heavy 11 gauge steel, the Leg Blaster (U.S. Patent #4986536) gives you the benefit of all versions of squatting while reducing stress on lower back and knees: full or parallel squat, front squat, hacks, sissy squat, plus standing calf raises, even lunges.
Squatting is the best exercise for developing the thighs and building lower body strength. But aside from the pain of holding the barbell on your shoulders, heavy squatting is hard on the knees and lower back and will enlarge the buttocks and waist. Now it is possible to develop your legs without having to endure the discomfort of barbell squats.
The harness fits over your shoulders, weighs 25 pounds, is comfortably padded at body contact points, 43 inches long from tip to tip and has a stabilizing latch for easy connection to the rack, preventing tipping while loading with either regular or Olympic plates (not included). The side weight bearing arms of the harness angle downward giving you a lower center of gravity, making it easier on knees and low back. You'll find it safer and more enjoyable to build, shape and define your legs.
The Leg Blaster rack holds the harness while you load it.
The harness is engineered to hug your ribcage when you squat with your upper body in an erect position, making it unnecessary to use a lot of weight to get to get results. Even though the unit is very strong, it is not necessary (or possible) to use much over 200 pounds when squatting in this fashion. The best I've done is 10 reps with 180 pounds. I've been squatting exclusively with it for over 20 years.
Your hands are free while squatting so you hold on to the balance bar to prevent unbalanced crooked reps. You stand on the secure footplate, making the rack entirely free standing and there is no need to bolt it to the floor. It's compact size (32 by 42 inches) allows you to fit it into the most crowded gym.
And it's easy to put together, there are only 3 bolts to attach: Using two 3/4 inch wrenches, first attach the balance bar in the lower hole if your are shorter, or the upper hole if you are taller than 5 foot 9 inches. Next, slide the vertical member over the rear vertical tube, insert the two bolts and tighten. Put the end caps on the rack, load it up and it's ready to use!
It's great for calf raises too. You will not find a better way to squat or do standing calf raises.
