Home Gym Safety With Babies: Treadmills, Weights and Bikes

How to baby proof a home gym: the risks of treadmills, weights and bikes, and how a closed door, a gate and one safety key help.

6 min read

Baby proofing a home gym comes down to a short list. Supervise your child at all times around the equipment. Keep the room closed off with a lock or a gate. Unplug the machines, take the safety key out and keep weights out of reach.

The AAP backs the supervision, unplugging, safety key and room-lock advice, and it warns about dropped weights. The closed door or gate is an extra layer Baby Proof Me suggests, and it never replaces watching your child.

Big Machines, Big Dangers for Little Kids

The AAP describes treadmills, ellipticals, rowing machines and stationary bikes as big machines that pose big dangers to little kids. Falls from these moving machines can lead to head trauma, concussions and broken bones. That is before you count belts, pedals, cords and weights.

Each piece of equipment has its own way of hurting a small child, so the fixes differ a little by machine. The AAP’s guidance on home exercise equipment child safety covers them together, and the basic habits overlap: watch your child, limit access, and cut power.

A gym is also one room in a larger house. A room-by-room walkthrough helps you catch the hazards outside the workout space.

Treadmill and Home Gym Safety With a Toddler in the House

The AAP lists five key considerations for keeping children safe around home gym equipment:

  1. Supervise. The AAP’s first point is that young children need to be supervised at all times around home gym equipment. Everything else here sits on top of that.
  2. Choose the location carefully. The AAP says exercise machines should not be set up in areas where children regularly play, such as the basement. If your basement is also the play space, baby-proofing the basement deserves its own plan.
  3. Unplug when you are done. The AAP says treadmills, stationary bikes and other workout machines should be unplugged when not in use.
  4. Remove the safety key. When a machine is not in use, the AAP says to take out the safety key and keep it in a separate, secure location.
  5. Consider a lock on the room. The AAP says to think about installing a lock on the workout room itself, if possible.

A closed door or a gate is a related idea from Baby Proof Me. It is not AAP advice, and it works as a layer on top of step one.

How to Baby Proof a Treadmill

The treadmill has the most specific hazard on the list. The AAP says little hands that get caught under the moving belt can suffer scrapes, friction burns and even finger amputations. It also says children have been entrapped, pinned and pulled under the equipment’s rollers.

Trying to child proof a treadmill means stacking layers, because no single fix covers every gap. A small child can reach a machine that is plugged in, or a console with a key sitting in it. The unplugging and safety key steps above address those two gaps.

If a child is hurt on gym equipment, call 911. Call your pediatrician with questions about any injury. The AAP has more at HealthyChildren.org.

The Safety Key: Remove It and Store It Separately

Many exercise machines require a safety key in order to operate, the AAP says. Take it out when you finish. Then store it in a separate, secure location, as the AAP advises, rather than leaving it on the machine.

Separate means away from the treadmill. If the key stays clipped to the console, a child can reach it.

The key is one layer. Unplugging the machine adds another, and a closed-off room adds a third.

Peloton Tread+ Recall

In May 2021, the CPSC announced a recall of the Peloton Tread+ treadmill, model number TR01. The notice says adult users, children, pets and objects can be pulled underneath the rear of the treadmill, posing a risk of injury or death. It reports that a 6-year-old child died after being pulled under the rear of the treadmill.

Peloton received 72 reports of adult users, children, pets and/or objects being pulled under the rear of the treadmill, including 29 reports of injuries to children.

Anyone trying to baby proof a Peloton Tread+ should read the CPSC recall notice first. If you own that model, check the notice for model number TR01 and follow what it says.

Weights: Dumbbells and Plates Belong Out of Reach

The AAP says weights accidentally dropped on small bodies can result in broken bones, internal organ damage, suffocation and possibly death. A toddler does not need to lift anything for this to happen. A dumbbell pulled off a bench or a plate tipped from a stack can do the damage.

The fix is distance. Dumbbells and plates belong out of a child’s reach.

If you are wondering how to child proof a weight rack, the AAP’s concern is the weights themselves. A rack that holds loaded plates, or a floor with a loose set of dumbbells, puts weight within a child’s reach. Put weights back after every workout, and keep the room closed so a small child cannot get to the weights while you are elsewhere.

Dressers and bookcases in other rooms are a separate tip-over problem. Anchoring furniture against tip-overs is where that work starts.

Stationary Bikes: Rotating Parts and Cords

A bike looks calmer than a treadmill, which is part of the problem. The AAP names the rotating parts of a stationary bicycle, alongside the treadmill belt, as a place where little hands get caught and hurt. A spin bike or exercise bike needs the same caution as any other machine.

Cords belong in the same conversation. The AAP says power and heart rate monitor cords can pose a strangulation risk. A cord that dangles from a machine is part of the hazard.

The matching fix is the same set of habits. Supervise, unplug the bike when you finish, and keep the room closed off. A bike that is unplugged and behind a shut door gives a curious baby fewer ways in.

How to Baby Proof a Home Gym Door With a Lock or Gate

Supervision handles the minutes you are in the room. The door handles the minutes you are not.

The AAP says to consider a lock on the workout room itself, if possible. If a lock is not an option, keeping the door shut or gating the doorway is a related approach from Baby Proof Me.

Picture this: you finish your workout, head to the kitchen for water, and leave the gym door open. Your toddler, who has been playing in the hallway, wanders in toward the machine. It takes a few seconds.

If you are comparing baby gates for doorways, Baby Proof Me’s Mesh Retractable Baby Safety Gate is one option for a gym. Its product listing says it fits doorways and hallways and rolls up when not in use. It has a dual-rotation lock with one-hand operation and no bottom bar. It comes with brackets and screws for mounting.

The gate is not a toy, should be used only for its intended purpose, and is not a substitute for adult supervision. Use it as one way to keep a gym room closed off when no adult is in it, and keep watching your child whenever they are near the equipment.

Questions Parents Ask About Kids and Treadmills

At What Age Is It Safe for a Child to Use a Treadmill?

The AAP’s guidance on home exercise equipment names no safe age. That also covers the common question of whether a 3-year-old can use a treadmill.

The AAP’s advice is to supervise young children at all times around the equipment, consider a lock on the workout room, and keep machines out of areas where children regularly play. Follow that advice and ask your pediatrician about your own child.

Can You Use a Treadmill While Wearing a Baby?

AAP guidance on home exercise equipment does not address wearing a baby on a treadmill. The AAP’s advice is supervision and keeping machines away from children. That guidance does not say whether a carrier changes the picture.

Ask your pediatrician before you try it. They know your baby’s age, size and health, and can answer in a way a general article cannot.

After Every Workout: A Short Routine

Make the end of a workout a fixed routine. Unplug the machine. Pull the safety key and store it in a separate, secure spot. Put dumbbells and plates out of reach. Check that no cord is dangling from the machine.

Then close the gym door and lock it if you can, or put the gate across the doorway. Keep the routine the same every time, and keep supervising whenever your child is near the equipment.
