The pandemic home gym boom created a massive secondary market for fitness equipment that's still going strong. Your unused gym equipment is probably worth more than you realize.
Peloton bikes: $400–$1,000+ depending on model and condition. Even the original model brings $400–$600. The Bike+ fetches $700–$1,000. Peloton treads: $1,000–$2,000. The brand premium is enormous.
Treadmills from NordicTrack, Precor, and LifeFitness: $200–$800 depending on model. Commercial-grade machines bring premium prices. Even basic residential treadmills in working condition bring $100–$200.
Free weights are basically cash by the pound. Iron plates sell for $0.50–$1.00/lb. A full Olympic set (300 lbs) is worth $150–$300. Dumbbells, kettlebells, and specialty bars all have active buyers.
The biggest mistake: hauling gym equipment to the dump because you assume nobody wants it. With us, that Peloton collecting dust earns you $200–$500 in credit. That weight set in the corner earns $75–$150. Your 'junk' gym pays for its own removal.
