Spirit Fitness CSI-BCTE i-Strength Dual Biceps Curl/Triceps Extension

No trade-off — the CSI-BCTE runs on a commercial-grade steel frame and a fully enclosed electronic resistance module, backed by Spirit's Commercial warranty tier, the same build standard as Spirit's mechanical weight-stack duals.

The CSI-BCTE replaces the mechanical weight stack and pulley system found on Spirit's CSD dual machines with an electronically adaptive resistance module, but the frame underneath is built to the same commercial standard: commercial-grade steel with a high-quality electrostatic powder coat finish, rated for a 350 lb max user weight. The resistance module itself is fully enclosed, protecting the electronics from the daily contact and impact of a busy gym floor. Spirit Fitness backs the CSI-BCTE with a Commercial warranty tier, including a 10-year frame warranty, for full dues-paying facility use, not just light residential duty. Blue Sky Fitness Supply is an authorized Spirit Fitness dealer, so that commercial coverage is enforceable through us for the life of the warranty period.

It ships in two cartons — a 112.4 lb electronics carton and a 229.7 lb frame carton — with liftgate delivery included by default, and the manual calls for at least two people to assemble it.

This machine ships freight in two separate cartons: a 30.1" x 29" x 19.1" carton weighing 112.4 lb, and a larger 48" x 38.2" x 22.2" carton weighing 229.7 lb, with liftgate delivery included by default. Inside, it arrives disassembled with the main frame, resistance module, touchscreen console, seat, arm pad, and a full hardware kit including every tool needed. Spirit's assembly instructions are broken into clearly numbered steps with matched hardware packs, and two people working together typically complete setup within about an hour. Professional installation is also available through Blue Sky Fitness Supply if you'd rather not assemble it yourself.

Contact Blue Sky Fitness Supply first — we handle the warranty claim and coordinate sourcing the replacement part or module, rather than leaving you to navigate Spirit Fitness's service line alone.

If the console, resistance module, or any other part needs attention, Blue Sky Fitness Supply manages the claim on your behalf and coordinates with Spirit Fitness's authorized service network to source the fix. All repairs must be preauthorized before work begins, and the console and resistance module carry their own 2-year parts and 1-year labor terms under the Commercial warranty. Spirit Fitness's own service line is also available directly if you'd rather reach out yourself, but it's never required — Blue Sky manages the process either way. Keep your bill of sale after delivery, since it may be requested if service is needed.

A single Commercial-tier warranty: 10 years on the frame, 5 years on bushings, bearings, shocks & pulleys, 2 years on the console & resistance module, 1 year on remaining parts & labor, and 6 months on upholstery.

Spirit Fitness backs the CSI-BCTE with one Commercial-tier warranty that applies to dues-paying facility use. The frame, welds, and cams carry a 10-year warranty, while the bushings, bearings, shocks, and pulleys are covered for 5 years. The touchscreen console and electronic resistance module get their own 2-year parts term, and everything else — paint, finishes, cables, grips, pull-pin components, rail wheels, and attachments — carries 1 year, alongside a 6-month upholstery term. Labor is covered for 1 year, and Blue Sky Fitness Supply handles the claim on your behalf so the warranty is something you actually use through one point of contact. Warranty registration must be completed online within 10 days of the delivery date to validate coverage.

It supports users up to 350 lb, with an adjustable seat, multiple grip options, and a pivoting curl/extension bar that accommodates a range of forearm lengths.

The CSI-BCTE is rated for a 350 lb max user weight, and its ergonomics are built around fitting a range of body sizes rather than one average frame. Adjustable seat height sets the elbow in line with the machine's pivot point, and the curl/extension bar itself pivots to accommodate different forearm lengths so the resistance tracks naturally through the full range of motion. Multiple grip options on the handles let users find a comfortable hand position for either the curl or the extension movement. The angled arm pad keeps the upper arm supported and limits shoulder involvement, so users of different sizes can all keep the load on the target muscle.

An electronically adaptive resistance module replaces the weight stack entirely, delivering 15 to 190 lb of resistance through 4 selectable modes — Pure, Eccentric, Isokinetic, and Elastic — set from the 10.1" touchscreen.

The CSI-BCTE uses Spirit's i-Strength system: an electronically adaptive resistance module that generates 15 to 190 lb of resistance without a single plate or pulley. Pure mode mimics traditional lifting, letting users slide a touchscreen bar to set resistance for both the concentric and eccentric phases of the rep. Eccentric mode lets users add 10% to 50% more resistance specifically to the lowering phase, a technique normally reserved for a training partner or specialized equipment. Isokinetic mode holds movement speed constant across 5 levels regardless of effort, a style traditionally used in rehabilitation settings, while Elastic mode ramps resistance up through the range of motion like a resistance band, across 15 levels. Every mode's console tracks live data — repetitions, total pounds lifted, and calories — and a built-in Strength Test can recommend a starting resistance for muscle endurance, hypertrophy, or power goals.

The curl trains the biceps on the front of the upper arm; the extension trains the triceps on the back. Together they cover balanced arm development from one seated station.

The CSI-BCTE trains both major muscle groups of the upper arm from a single seat. The biceps curl movement works the biceps brachii on the front of the upper arm, which flexes the elbow, while the triceps extension works the triceps on the back of the arm, which straightens it. The angled arm pad and pivoting bar keep the shoulder out of the movement, so the digital resistance loads the target muscle directly rather than letting momentum or shoulder drive take over. Because the resistance is set digitally per exercise, switching between the two movements takes a touchscreen adjustment instead of re-racking a pin, letting users move through balanced arm training faster. That combination makes the CSI-BCTE a practical staple for general members and athletes building even biceps-to-triceps strength.

It occupies about 42" L x 57.8" W and stands 42" tall, with a low-profile design that keeps sightlines open on a busy floor.

The CSI-BCTE has a setup footprint of about 42 inches long by 57.8 inches wide and stands 42 inches tall, keeping it compact for a dual-function commercial station. Spirit's low-profile design philosophy carries over from the mechanical CSD line, so the machine doesn't block sightlines across a training floor the way a taller tower would. Steel feet with rubber foot covers keep the unit stable and protect flooring once it's bolted in place. Because it trains both the biceps curl and triceps extension from one seat, that footprint effectively replaces two separate arm stations.
