Body-Solid's inner outer thigh machine lineup spans two very different product categories: standalone machines with their own weight stack, and gym attachments that add inner/outer thigh training to a multi-station gym you already own. If you're comparing the DIOT, S2IOTX, GIOTB, and GIOT9, the fastest way to sort them is by tier — attachment versus standalone, and entry-level versus premium.
Tier 1: Attachments — GIOTB and GIOT9 Inner Outer Thigh Attachments
GIOTB Price: $1,520 | GIOT9 Price: $1,520 | Type: Gym Attachment | GIOTB Weight: 117 lbs., 55.1"L x 75.3"W x 33.5"H | GIOT9 Weight: 121 lbs.
The GIOTB Inner Outer Thigh Attachment and GIOT9 Inner Outer Thigh Attachment are both priced at $1,520 and are the most budget-friendly way into inner/outer thigh training — as attachments, they're designed to add this movement to a compatible Body-Solid multi-station gym you already own rather than functioning as a standalone machine. At 117 lbs. and 121 lbs. respectively, they're also by far the lightest options in this lineup, both backed by Body-Solid's commercial/lifetime warranty.
Because they're attachments rather than standalone machines, the GIOTB and GIOT9 are the right call only if you already own a compatible Body-Solid gym station to mount them to — check your specific gym's attachment compatibility before ordering either one.
Best for: gym owners who already have a compatible Body-Solid multi-station gym and want to add inner/outer thigh training at the lowest cost in this lineup.
Tier 2: S2IOTX Series 2 Inner and Outer Thigh
Price: $3,140 | Weight Stack: 160 lbs. standard (235 lb. upgrade) | Dimensions: 77"x37"x57" | Product Weight: 385 lbs.
The S2IOTX Series 2 Inner and Outer Thigh is a standalone machine with its own 160 lb. weight stack (235 lb. upgrade available), so it doesn't require an existing gym to attach to — it's a dedicated station on its own footprint. At $3,140 starting, it sits squarely between the attachment tier and the top-tier DIOT, giving you standalone convenience without the DIOT's full price tag.
Best for: facilities that want a dedicated standalone inner/outer thigh station without needing a compatible gym to attach it to, at a mid-range price.
Tier 3: DIOT ProDual Inner Outer Thigh
Price: $4,710 | Weight Stack: 210 lbs. standard (310 lb. option) | Dimensions: 76"L x 36"W x 62"H | Product Weight: 475 lbs.
The DIOT ProDual Inner Outer Thigh is the premium standalone option, with a heavier 210 lb. stack (310 lb. upgrade) and Body-Solid's full commercial warranty. It's built for high-volume commercial use where a heavier resistance ceiling and a fully dedicated, single-purpose station matter more than initial cost.
Best for: commercial facilities that want the heaviest available resistance and a dedicated ProDual-grade standalone machine.

Attachment vs. Standalone: Which Tier Is Right for You?
The first decision isn't DIOT vs. S2IOTX vs. GIOTB — it's whether you need an attachment or a standalone machine. If you already own a compatible Body-Solid multi-station gym, the GIOTB or GIOT9 attachment adds inner/outer thigh training for the lowest cost in this lineup. If you don't have a compatible gym, or you want a dedicated station regardless, you're choosing between the S2IOTX's mid-tier 160 lb. stack and the DIOT's premium 210 lb. stack based on budget and expected training load.
