The SKEISO JXS-037C is an adjustable flat, incline and decline bench that supports upper-body pressing, supported pulling, shoulder work, arm training, core exercises and lower-body support work when paired with the appropriate weights or rack. Its optional AH04 attachment adds plate-loaded leg extensions and leg curls, while the optional AH05 creates a preacher-curl station. The bench itself does not supply resistance, so a complete workout plan must separate what the base bench supports from what requires weights, a rack or an add-on.

Flat bench exercises
A flat position provides the most familiar base for dumbbell presses, flyes, pullovers and lying triceps extensions. It can also support a barbell bench press when correctly positioned inside a compatible rack. For one-arm rows, the bench gives the non-working hand and knee a stable support point. Hip thrusts and split squats use the bench as body support rather than as resistance.
Do not infer a weight rating from the frame size. The current verified product information does not state a tested user-and-load capacity, so load-capacity claims should not be invented. Users should follow the product instructions and choose an appropriate setup for their body, weights and surrounding equipment.
Incline bench exercises
Raising the backrest changes torso position for incline dumbbell presses, supported rows, seated shoulder presses and incline curls. A shallow incline can shift a press toward the upper chest, while a steeper seated position supports overhead pressing. For chest-supported rows and rear-delt raises, facing the pad reduces the need to hold the torso unsupported.
- Chest: incline dumbbell press and incline fly.
- Back: chest-supported row and pullover variations.
- Shoulders: seated press, lateral raise and supported rear-delt raise.
- Arms: incline curl and seated overhead triceps extension.
Decline and core exercises
A decline setting can support decline pressing and selected trunk exercises when the user can maintain a secure body position. Crunches, reverse crunches and controlled knee-tuck variations can be programmed without turning the bench into a dedicated abdominal machine. The safest usable range depends on the selected bench position, the user's control and the surrounding setup.
Optional AH04 leg extension and curl exercises
The AH04 is a separate plate-loaded leg extension and curl attachment designed for the JXS-037C. Leg extensions primarily train the quadriceps through knee extension. A compatible curl configuration trains the hamstrings through knee flexion. The attachment uses a approximately 1.97 × 1.97 × 0.079 in frame and has a verified net weight of approximately 48.5 lb, but its effective resistance depends on the plate load, lever position and exercise setup.
Confirm current compatibility, availability and package contents before buying. The base JXS-037C should not be advertised as including the AH04 unless the selected offer explicitly includes it.
Optional AH05 preacher-curl exercises
The AH05 adds a supported preacher-curl position for elbow-flexion work. It can be paired with an appropriate dumbbell, straight bar or curl bar depending on the user's setup. The pad stabilizes the upper arm, but it does not eliminate the need for controlled range of motion and a manageable load. The AH05 uses a approximately 1.97 × 1.97 × 0.098 in frame and has a verified net weight of approximately 24.3 lb.
What are the advantages of an FID bench?
- One support platform, several torso angles: flat, incline and decline positions broaden press, row, shoulder, arm and core choices.
- Works across equipment types: the bench can support dumbbell training and compatible rack, Smith or cable setups.
- Chest-supported pulling: incline positions help support rows and rear-delt work.
- Expandable lower- and upper-body options: the AH04 and AH05 add focused leg and arm stations without changing the base bench.
- Heavy base construction: the verified approximately 2.95 × 2.95 × 0.118 in base-bench frame and approximately 105.8 lb net weight describe the physical build without substituting for an unverified load rating.
Who is the JXS-037C best for?
The JXS-037C suits buyers who need one adjustable bench for dumbbell work and a compatible rack, Smith machine or cable trainer. Its verified base-bench size is approximately 52.8 × 23.8 × 21.8 in (L × W × H). Allow extra room for entering the bench, adjusting the backrest, moving weights and positioning it inside another station.
It may not be the right choice for someone who only needs a simple fixed flat bench, wants a bench advertised as foldable, or requires a published load rating that is not currently verified. Compare the decision factors in the adjustable bench versus flat bench guide.
Setup and buying checks
- Confirm the bench fits the rack or machine and the intended bar path.
- Check that the chosen angle supports the exercise without frame interference.
- Verify whether the AH04 or AH05 is included or sold separately in the current offer.
- Keep dumbbells, plates and adjustment points clear before changing positions.
- Use the assembly manual for installation and inspection; use qualified coaching for unfamiliar exercise technique.
Frequently asked questions
What does FID mean?
FID means flat, incline and decline—the three main bench-position categories supported by the adjustable design.
Does the JXS-037C include weights or a rack?
No assumption should be made that external weights or a rack are included. Check the current product package before ordering.
Are the leg and preacher attachments included?
The AH04 and AH05 are optional add-ons and should be treated as separate products unless a current bundle explicitly states otherwise.
Can the bench be folded for storage?
Foldability is not a verified feature in the current product records, so buyers should not plan around a folding function.
Review the exact configuration: visit the JXS-037C product page for current specifications, optional attachments and purchase details, or browse the SKEISO weight bench collection for a compatible setup.
