Adjustable Dumbbell A dial-select dumbbell that picks up only the weight plates matching the chosen setting, replacing a rack of 10–15 fixed dumbbells. 113 parts · 6 subsystems

Adjustable Kettlebell A kettlebell whose handle-and-core unit selectively locks to a set of nested weight shells, giving 5–6 weights in one bell. 47 parts · 6 subsystems

Adjustable Weight Bench A flat/incline/decline strength-training bench whose back pad pivots on a ladder-and-catch mechanism to lock at multiple angles. 38 parts · 7 subsystems

Air Assault Bike A fan bike: pedaling and pushing the moving handlebars spin a large air fan through a belt drive, so resistance climbs with effort, while a battery console tracks cadence and calories. 115 parts · 8 subsystems

Anti-Gravity Treadmill A rehabilitation treadmill that encloses the runner’s lower body in a pressurized air chamber, unweighting them by up to 80% of body weight using differential air pressure. 96 parts · 9 subsystems

Baseball Pitching Machine A two-wheel training machine that grips a baseball between counter-rotating urethane wheels and throws it at a set speed and spin, with a ball feeder, electronic speed control, and an adjustable tripod head. 144 parts · 9 subsystems

Belt Squat Machine A squat machine that loads the hips through a belt instead of the spine, using a lever arm or pulley system to route plate weight beneath a standing platform. 49 parts · 8 subsystems

Boxing Ring An elevated, roped platform used for boxing matches and training, with resilient floor, rope perimeter, and corner padding for safety. 78 parts · 7 subsystems

Cable Crossover Machine Dual-stack functional trainer with two adjustable, height-settable pulley columns and a chin-up bar. 117 parts · 10 subsystems

Cable Functional Trainer A dual-stack cable machine with independently-adjustable pulleys at multiple heights, enabling hundreds of variable-angle exercises using interchangeable cable attachments. 95 parts · 7 subsystems

Climbing Auto-Belay A wall-mounted device that takes up a climber’s slack on a retracting webbing line and, on a fall, lowers them at a controlled speed using a magnetic eddy-current brake with no friction parts or user input. 49 parts · 7 subsystems

Climbing Ladder Ergometer A rotating ladder-rung climb simulator where the user pushes a series of rungs downward; the belt loops continuously and the user must keep pace or slip backward, creating an infinitely scalable resistance. 136 parts · 8 subsystems

Curved Manual Treadmill A motorless treadmill whose concave slat belt is driven by the runner’s own footstrike: stepping onto the front of the curve pushes the belt rearward, with speed set entirely by foot placement and an optional magnetic brake adding resistance. 411 parts · 8 subsystems

Elliptical Trainer Front-drive elliptical cross-trainer with motorized incline, magnetic eddy-current resistance, moving and static handlebars, and a console. 111 parts · 8 subsystems

Exercise Bike A smart indoor spin bike with a heavy flywheel, electronically controlled magnetic resistance, and a touchscreen console for guided rides. 93 parts · 10 subsystems

Glute-Ham Developer A posterior-chain bench (GHD) that clamps the ankles between rollers and a footplate so the user can perform glute-ham raises, back extensions, and GHD sit-ups over a split hip pad. 41 parts · 7 subsystems

Hack Squat Machine A plate-loaded squat machine: the user stands on a footplate under angled shoulder pads and drives a sled up two inclined rails on linear bearings, with spring-assisted catches handling the rack and release. 61 parts · 6 subsystems

Hydraulic Circuit Trainer A manual-pump hydraulic resistance trainer where fluid flow through adjustable valves creates smooth load, with no motors or electronics. 61 parts · 8 subsystems

Inversion Table A pivoting bench that rotates a strapped-in user past horizontal to hang head-down by the ankles, using body geometry as the balance control and a tether to limit the inversion angle. 42 parts · 7 subsystems

Lat Pulldown Machine A selectorized cable machine: a seated user pulls a wide bar down against a guided weight stack, with the load routed through a pulley train and the thighs braced by an adjustable hold-down pad. 58 parts · 7 subsystems

Leg Press Machine A 45-degree plate-loaded leg press: a welded steel frame carries an angled sled on linear guides, loaded with weight plates on horns and stopped by spring-loaded safety catches. 54 parts · 7 subsystems

Mini Stair Stepper A compact floor-standing stepper whose two pedals alternate against hydraulic cylinder resistance, with optional resistance bands for the upper body. 56 parts · 6 subsystems

Multi-Station Home Gym A cable-driven selectorized home gym with a stacked weight plate column feeding multiple training stations through a pulley-and-cable network. 105 parts · 11 subsystems

Outdoor Gym Station A fixed public-park exercise station made of galvanized steel with pivot-hinged arms and body-weight resistance, designed for durability in outdoor weather. 129 parts · 7 subsystems

Pec Deck Machine A selectorized chest machine: the user presses two padded arms together, each swinging on a pivot bearing, and a cam routes the motion through a cable to a guided weight stack so the load stays even across the arc. 63 parts · 6 subsystems

Percussion Massage Gun A handheld percussive therapy device in which a brushless motor drives an eccentric cam that reciprocates a piston-mounted head 10-16 mm into soft tissue at 1,200-3,200 strokes per minute. 71 parts · 8 subsystems

Pilates Reformer A sliding-carriage exercise apparatus in which the user pushes or pulls a wheeled platform against selectable spring resistance along frame rails. 73 parts · 8 subsystems

Pneumatic Resistance Machine A single-joint or multi-joint exercise machine whose resistance comes from air cylinders, providing load-independent force that scales with user speed and input pressure. 52 parts · 7 subsystems

Power Rack A 4-post squat/power rack with bolt-on strength-training attachments. 88 parts · 12 subsystems

Push Sled A flat sled that slides on rails, loaded with weight plates, which the user pushes across a gym floor for power and conditioning drills. 42 parts · 6 subsystems

Rotating Climbing Wall A treadmill-like climbing device where a continuously rotating vertical panel loop presents an infinite sequence of climbing holds at variable speed and angle. 190 parts · 8 subsystems

Rowing Machine An air-resistance indoor rower with a flywheel fan unit, sliding seat, and a battery-powered performance monitor. 60 parts · 8 subsystems

Ski Ergometer A vertical air-resistance ergometer that simulates Nordic ski double-poling: pulling two cord-mounted handles downward spins a damped flywheel through one-way clutches while a performance monitor computes power from flywheel deceleration. 43 parts · 7 subsystems

Smart Fitness Mirror A wall- or stand-mounted fitness mirror: an LCD panel behind two-way mirror glass, with a camera for form tracking, a speaker array, and a touch overlay. 36 parts · 10 subsystems
