How Much Weight Can a Body Weight Support System Offload?
A Body Weight Support system offloads anything from a few pounds to a large share of your weight, and the amount is set for each person. A LightSpeed Lift system offloads from 0 to 60 pounds. Two things set the amount: the strap or belt you wear, and the height of the mounting points.
How much you use depends on your goal, and you can change it from one set to the next. Here's what each part of the system does.
How much each LightSpeed Lift strap and belt offloads
The lift comes from elastic cords in the strap or belt you clip to the frame.
Strap or belt
Lift
Made for
Lift Straps (pair)
0 to 40 lb, adjustable
Everyday training. They attach to the Magic Shorts.
Super Lift Straps (pair)
0 to 60 lb, adjustable
More lift, and more side-to-side support for balance.
Universal Lift Belt
Up to 40 lb
Worn over regular clothes, with leg wraps. No changing needed.
Super Lift Belt
Up to 60 lb
Users with balance problems, or who need more support.
Pediatric Lift Belt
Up to 25 lb
Users who weigh under 60 lb.
Overhead Safety Harness
No lift
Fall protection. It comes with the LSX-500.
At 0 pounds the straps still do something. They keep you centered and steady, with no weight taken off.
The LS-300 comes with Lift Straps and a Universal Lift Belt, so it lifts up to 40 pounds as it comes. Add the Super Lift Straps or the Super Lift Belt, ordered as extras, and it lifts up to 60.
25 pounds off a 50-pound child is half their weight.
So the same strap lifts a bigger share of a lighter person. The Pediatric Lift Belt is calibrated for users under 60 pounds for that reason.
Changing the lift as you go
You set the lift by moving the mounting points up or down the uprights. A coach or therapist can change it between exercises or between sets. Nothing needs recalibrating.
As strength and balance come back, the mounting points are moved a little at a time to take lift away.
How much offload is right for you
It depends on why you're using it.
Training: athletes use lighter lift to keep training with less stress on their joints.
Low-impact exercise: people walking or running for fitness pick a level that feels steady and comfortable.
Rehab and gait training: patients often start with more lift and step it down as they heal.
In a clinic, your physical therapist or physician sets the amount. In training, it's you or your coach. Always check with your physician if you have a medical condition, are pregnant or are coming back from surgery.
Which system fits the support you need
All three systems lift from the hips, so you walk and run with your natural stride.
LS-300: 0 to 40 lb, or 60 with the Super Lift Straps or Belt. 1.5-inch steel tubing and a low profile. Made for home gyms.
LSP-400: 0 to 60 lb. 2 x 3-inch steel tubing for extra stability. Made for training centers, rehab clinics, fitness centers and upscale home gyms.
LSX-500: 0 to 60 lb. Taller uprights for taller and heavier users, plus the overhead safety harness. Made for balance training, neurological rehab and sprint work.

There's no maximum user weight on any of the three systems.
Each one stands over the treadmill you already have. Your treadmill has to be under 40 inches wide and sit at least 1.9 inches off the floor (1.2 inches for the LSX-500). Check your treadmill
60 pounds on any LightSpeed Lift system, with the Super Lift Straps or the Super Lift Belt. The standard Lift Straps and the Universal Lift Belt go up to 40 pounds. On the LS-300 the Super Lift Straps and Belt are ordered as extras.
