Bodytone Solid Grow SG57 hack squat

The Bodytone Solid Grow SG57 is a professional hack squat with an optimised movement angle and reinforced lumbar support, loaded by 50 mm Olympic discs. The inclined rail guidance places the quadriceps under deep tension while the strengthened back and lumbar pad holds the spine against the frame, which is what allows the movement to be pushed hard without the risks that accompany a heavily loaded free squat.

It belongs to the Solid Grow line, the entry to mid range series designed for small gyms, independent coaches and premium home gyms. Recommended maximum load is 101 kg, and a 50 kg disc kit per machine is the usual accompanying order. Discs are not supplied.

Technical specification

Where a hack squat belongs

The machine is specified by small and medium gyms and by independent coaches supervising experienced clients on squatting movements, and by premium home gyms. Its value against a free squat is the back support: a hack squat lets a coach load the quadriceps deeply while removing the trunk stabilisation demand, which is exactly what is wanted in a hypertrophy block or in the later stages of a knee rehabilitation programme.

Plan clear access at the shoulder pads so a user can step in and out, and side clearance for loading and stripping discs. Rubber flooring under the machine protects the slab and reduces the noise of plates being seated, which matters in a small room or a converted space more than on a large gym floor. Exact dimensions and the anchoring requirement are confirmed at quotation stage against the current Bodytone specification, and we can produce a layout study for the room.

Frequently asked questions

Is 101 kg enough?

It is the recommended maximum for this reference in the Solid Grow range, which is positioned for entry to mid range use. Facilities training strength athletes should look at the Solid Rock or SRX plate loaded ranges, which we can quote alongside for comparison.

How does it differ from a leg press?

A hack squat keeps the user upright with the back supported and the feet below the body, so the movement resembles a squat. A leg press seats the user with the legs pushing away from the torso. The two load the quadriceps through different joint angles and most complete leg zones include both.

Are discs included?

No. Discs in 50 mm Olympic format are quoted separately, with a 50 kg kit per machine as the recommended starting point. Quotations are issued within 24 working hours.
