Aside from weights, a stationary bike may be the easiest piece of home gym equipment to move.
If you can slide a towel, flattened cardboard box, or felt gliders (designed for moving furniture) beneath the bike, you can move the stationary bike with just one person. If the bike must be lifted up or down stairs, you'll need at least two people. Take care to secure any moving parts with bungee cords or packing tape to prevent injury, and remember to lift with your legs when you move your stationary bike. If the bike is electric, wrap up the power cord and secure it to the bike before moving.
Elliptical machines are often awkwardly shaped and unwieldy. In some cases, it's simply easier to disassemble the equipment and put it back together at the new location, placing all the hardware in a plastic baggy and using packing tape to attach it to the machine.
If you want to move an elliptical machine without taking it apart, you'll need at least two movers. If possible, leave the front end on the ground and use sliders or a towel to move the machine across the floor. If you must move the elliptical machine up or down stairs, use at least three movers (two for the front, and one for the back.) Take it stair-by-stair, stopping momentarily and resting the elliptical on the stair if anyone needs a break.
If your treadmill folds up, you're in luck. Simply wrap the power cord and secure it with a zip tie, and slide the treadmill along the ground on top of a towel, unless it's light enough for one or two people to lift.
If the treadmill doesn't fold, move it in the same careful manner as an elliptical, being sure to only move it by the sturdiest metal parts.
Like treadmills, many rowing machines fold up to make it easy to move them. Your biggest concern with a rowing machine is securing the handles, which can easily be done with zip ties.
Often times, when people think of a home gym, they think primarily of a home weight setup. Weightlifting machines present unique challenges in a move. You'll want to collect the manuals for your weightlifting machines, remove all the weights, and disassemble the equipment step-by-step.
Secure hardware (nuts, bolts, and screws) in plastic baggies and tape them to the corresponding piece of equipment. Make sure you don't lose your instruction manual so you can easily put the equipment back together at your destination. If you can't find the manual, you'll want to document the disassembly process with handwritten notes and photos.
Make sure to secure any moving parts with packing tape, bungee cords, rope, or zip ties, depending on their size and what you have available, as loose parts can damage walls or injure the movers.
Most oddly shaped gym equipment doesn't require boxes or crates; simply wrap it in moving blankets, bedding or towels to prevent scratches or damage.
If you decide to pack the weights in boxes, make sure to keep the boxes light. For instance, you may wish to move a 50 lb. weight by itself, but bundle 5, 10 and 25 lb. weights together in a sturdy box weighing less than 70 to 100 lbs. total.
Wrap weight bars in towels to prevent scratching and to keep the metal bars from damaging furniture and other items during the move.
As with free weights from your home gym setup, pack hand weights, medicine balls, yoga bricks, portable steps, and any other exercise equipment together in one box without making it too heavy.
Try to pack all your home gym equipment near each other in the moving truck or vehicle, making it easy to get back to your workout routine quickly after your move.
