The Dynasty Fitness DRE8041 Standing Total Arms is a dual-function selectorized machine covering both standing biceps curls and triceps extensions from one 160 lb Dynasty Flex-Stack station at a 1:1 felt weight ratio — with 13 arm position adjustments spanning 4 forearm length settings and 10 height positions, 360° rotating handles, included straight and cambered bars, and a cam resistance mechanism that varies the load through the movement arc to match the natural strength curve of the biceps and triceps. A 1000×650mm non-slip standing platform keeps the body grounded through both exercises. Built to commercial grade at 54.2"×42.3"×70.8".

• Dual-function design trains both biceps curls and triceps extensions from one standing station — switching between exercises requires only changing the arm position setting, covering both sides of complete arm development without a second machine or second footprint
• 4 arm length settings align the user's forearm pivot precisely with the machine's mechanical pivot for each individual's limb proportions, improving power transfer and movement smoothness through both the curl and extension arcs rather than forcing an approximate alignment that suits only average arm lengths
• Cam resistance mechanism varies the load through the movement arc to match the natural strength curve of the biceps and triceps — providing greater resistance where the muscles are strongest and reducing it where they are weakest, for a more complete and productive muscle stimulus per rep than a fixed resistance path delivers
• Dynasty Flex-Stack System delivers 1:1 felt weight — what you select is what you lift — and the included straight bar and cambered bar give immediate grip variety for both exercises without additional accessory purchases
