The Dynasty Fitness DRE8044 Seated Arm Curl/Extension is a dual-function selectorized machine covering seated biceps curls and triceps extensions from one chest-supported station — with dual-angle extended handles spanning 68° of motion that adapt to natural forearm rotation to maintain a neutral wrist through both exercises, a 2+3 arm adjustment system (2 positions for biceps, 3 for triceps) aligning each user's forearm length precisely, an ergonomic arm and chest pad, 8-position back pad, and an infinitely adjustable air-assist seat. Dynasty Flex-Stack System 1:1 felt weight ratio at 160 lbs. Built at 54.3"×47.5"×63.1".

• Dual-angle extended handles spanning 68° of motion adapt dynamically to the natural forearm rotation that occurs through both the curl and extension arcs — maintaining a neutral, comfortable wrist position throughout both exercises and reducing the joint stress that fixed-angle handles create when the wrist is forced to hold a position through the movement
• 2+3 arm adjustment system — 2 dedicated positions for biceps curl alignment and 3 dedicated positions for triceps extension alignment — ensures the machine's mechanical pivot point aligns precisely with the user's elbow joint for each exercise mode, producing smoother, more natural movement and better force transmission than a one-size-fits-all fixed arm position
• Ergonomically contoured arm pad and chest pad accommodate varying shoulder widths and keep the body in a natural supported alignment through both exercises, allowing the biceps and triceps to work in complete isolation without torso or shoulder compensation
• Dynasty Flex-Stack System delivers 1:1 felt weight at 160 lbs — the 8-position back pad and infinitely adjustable air-assist seat together cover every user body proportion to find the exact arm angle that produces the greatest biceps and triceps stimulus through the full range
