Description
The Bodytone Solid Grow SG51 is a plate-loaded belt squat station with a recommended maximum load of 77 kg on 50 mm Olympic sleeves. The load hangs from a hip belt rather than sitting on the shoulders, which removes axial compression from the spine. Light In Fitness supplies it at 1,595.20 EUR excluding VAT.
Squatting without loading the spine
In a barbell squat the load passes down the spinal column before it reaches the legs, so the lower back is always a limiting factor and often the first thing to fail. A belt squat applies the weight at the pelvis, below the spine entirely. The quadriceps and glutes receive the same work; the vertebral column receives none of it. For anyone with lumbar sensitivity, that is the difference between training legs and not training legs.
- Load applied at the hips through a belt harness
- Recommended maximum load of 77 kg
- 50 mm Olympic sleeves; plates not supplied
- Target muscles: quadriceps and glutes, without axial loading
High volume without accumulating fatigue
The second argument for a belt squat is volume. Because the trunk is not carrying the load, sets can be repeated far more often within a week before the athlete accumulates the systemic fatigue that heavy back squatting produces. Strength coaches use it as the accessory leg movement between heavy sessions; clubs use it as the leg station members can train hard on without needing to be taught a barbell squat first.
Who it is for
Solid Grow is Bodytone’s entry to mid-range plate-loaded line, sized and priced for studios, independent coaches and premium home gyms rather than for high-traffic commercial floors. The SG51 is specified in particular by coaches working with clients who have a history of back pain, and by residential installations where a squat rack is impractical.

Frequently asked questions
Is the belt included?
The harness is supplied with the station. Replacement belts are available separately, and on a busy site it is worth holding a spare, since the belt is the only consumable component on the machine.
Can it replace a squat rack?
For hypertrophy and general leg strength, largely yes. For athletes who need to develop trunk bracing under axial load, no: that adaptation only comes from loading the spine. Most facilities that install a belt squat keep a rack as well and use the two for different purposes.
Is 77 kg enough?
For the belt squat pattern, yes, in the context this machine is designed for. The movement is used for volume and for controlled loading rather than for maximal attempts, and 77 kg at the hips is substantially more demanding than the same figure on a barbell.
