The Nautilus Nitro Plus Preacher Curl delivers seated preacher curl bicep isolation with angled arm pad for minimal shoulder involvement, adjustable seat height, contoured non-slip arm pad, compact footprint, and heavy-duty Nautilus Nitro Plus commercial construction — 350 lb frame, 51"×41" footprint. The preacher curl machine is the gold standard for bicep isolation because the angled arm pad physically prevents the two primary compensations that allow other muscle groups to assist the curl: shoulder flexion (swinging the upper arm forward to generate momentum) and torso lean-back (using the spinal extensors and hip flexors to create a counterbalance). On a standing or seated dumbbell curl both compensations are available — the shoulder can flex forward and the torso can lean back as the weight becomes heavier, allowing stronger muscle groups to contribute. The preacher pad locks the upper arm against the angled surface through the full curl arc: the arm cannot move forward because the pad is in the way, and the torso cannot lean because it's unsupported behind the pad. The result is that the biceps brachii — the short and long heads — must produce all of the curling force from the fully lengthened position at the bottom of the arc through the fully shortened position at the top, without assistance from the anterior deltoid or any torso momentum. The angled pad angle on the Nautilus Nitro Plus is designed to optimize the loading through the biceps' active range — the angle positions the elbow at the joint angle where the biceps tendon is most favorably oriented for force production through the full curl arc. Adjustable seat height positions the user's arm correctly against the pad regardless of torso length — if the seat is too low, the shoulder is forced into flexion against the pad top; if too high, the elbow extends off the pad bottom, both of which compromise the isolation.

Contoured arm pad and non-slip grips for stability through the full curl arc. 350 lb Nautilus Nitro Plus commercial frame, 51"×41" footprint. Contact us for stack specifications. Remanufactured.

Angled Arm Pad · Adj. Seat — Shoulder and Torso Compensation Eliminated
Angled pad locks the upper arm through the full curl arc — the arm cannot flex forward (shoulder compensation) and the torso cannot lean back (momentum compensation) because the pad physically prevents both. The biceps must produce all curling force from full stretch at the bottom through full contraction at the top without assistance. Adjustable seat height positions the arm correctly against the pad for different user torso lengths — preventing shoulder forced into the pad top or elbow slipping off the bottom.
Contoured Pad · Non-Slip Grips · Compact 51"×41" · 350 lb Frame
Contoured arm pad distributes contact pressure across the full upper arm surface rather than concentrating it at a single point — reducing discomfort during heavy sets. Non-slip grips maintain hand position through the full curl without grip fatigue. 51"×41" footprint is compact enough for space-conscious strength circuits where dedicated bicep isolation is the goal. 350 lb Nautilus Nitro Plus commercial frame with commercial-grade upholstery.

1. How do I select weight on a selectorized machine?

Insert the weight pin into the desired stack hole; ensure it clicks into place before use.

2. What weight stack size should I choose?

Most base level weight stacks can accommodate even advanced lifters, but for the real weight-movers, look for the items with expansion stacks.

3. What maintenance is required?

Inspect guide rods and stack alignment monthly; wipe rods and replace worn bushings annually.

4. Is installation available?

Yes—schedule professional installation during checkout for a seamless setup.

5. What warranty covers these machines?

New units carry full OEM coverage; remanufactured units include a 12 month Build A Gym Guarantee.

30-Day Returns & Exchanges

Buy with confidence. Every Build A Gym order includes a 30-day window to return or exchange, whether you want a different size, color or configuration.
