BODYTEC PLATE LOADED PREACHER CURL (BICEPS ISOLATOR

Lock in, Curl Clean - Peak biceps, no cheating

• Strict form. Big peaks: A preacher-focused curl station engineered to take the swing out and pour the load into your biceps.
• Built for busy floors: Heavy frame, sealed pivot, and wipe-clean upholstery with Olympic plate loading.
• Biomechanics-first preacher pad: Oversized preacher pad with waterfall edge—broad, slightly concave top with a central taper to lock upper arms and reduce shoulder shrugging.
• Ergonomic twin grips mounted on a single lever; grips are slightly down-swept with chrome end sleeves for natural wrist alignment and reduced forearm strain.
• Single resistance horn (Olympic Ø50 mm) on the left side driving a through-shaft that powers both grips—keeps load centered and the motion perfectly symmetrical.
• A detachable “bicycle-handlebar” cross-grip that pins to the central boss between the two grips—converts the unit into a bar-style curl with multiple hand widths.
• Seat & pad cluster: thick high-density foam, industrial vinyl; seat height adjustable via a slotted/ratchet bracket under the seat.
• Wide, low base with rubberized feet for floor protection; arched right side upright side entry support.
• Olympic plate-loaded: Smooth torque through a central drive shaft; no cables = near-zero maintenance.
• Adjustable seat height: Dial in elbow-to-pivot alignment for users from beginner to pro.

Biomechanics

• Movement path: Elbow flexion against a rising moment arm; the curve peaks mid-range—right where the biceps produce maximum force—delivering strong stimulus through the “money zone.”
• Joint alignment: Adjustable seat lets the user align elbow axis with the machine pivot, protecting the elbow and keeping tension on the biceps.
• Cheat-free mechanics: The preacher support prevents torso rock and shoulder recruitment, emphasizing biceps brachii, with strong carryover to brachialis and brachioradialis when using neutral grips.
• Wrist comfort: Down-swept handles keep wrists neutral to reduce strain during heavy sets and high-rep finishers.

Types of exercises you can perform

1. Bilateral strict preacher curls (standard grip).
2. Close-grip curls (more long-head emphasis).
3. Wide-grip curls (more short-head emphasis).
4. Neutral-grip “hammer” preacher curls (with the bicycle-handlebar attachment or by gripping the down-swept sections).
5. Single-arm preacher curls (one handle at a time for unilateral focus).
6. Partials & overload reps in the mid/top range.
7. Tempo & eccentric-accentuated curls thanks to the smooth plate-loaded resistance.

Muscles targeted

• Primary: Biceps brachii (long head & short head).
• Secondary: Brachialis, brachioradialis, wrist/finger flexors (stabilization).
• Stabilizers minimized intentionally: Anterior deltoid and trunk activity reduced by preacher support to keep focus on elbow flexors.

Specs highlights (operations-friendly)

• Resistance: Olympic plates (Ø50 mm).
• Adjustability: Seat height; swappable cross-grip for hand-position variety.
• Drive: Central lever with sealed pivot hardware (bearing/bushing system).
• Finish: Industrial powder-coat; high-density foam; sweat-resistant vinyl
