A Home Gym With a Toddler in the House

The kit is in the corner of the living room, because there is nowhere else for it to be. And there is a small person in that room who has recently worked out how to move a dining chair.

So you do the sensible thing. You look up childproofing, and every answer you find is a storage answer: put it away, put it high, shut the door. You buy a shelf.

There is a problem with that, and it is not a small one. The most serious documented injuries to children from home exercise equipment did not happen because a child got at something that was put away badly. They happened while an adult was using the machine.

That changes what you buy, and it changes it in a direction most people do not expect.

What this covers

Free weights, bands, a suspension trainer and one cardio machine, in a room a child under about six also lives in. Not a locked garage, not a spare room with a door that stays shut — the ordinary case where the gym and the child share a floor.

Safety facts first, and named. In May 2021 the CPSC and Peloton announced a recall of the Tread+ treadmill after the death of a six-year-old child pulled under the rear of the machine, with 72 reports of adults, children, pets or objects being pulled under, including 29 reports of injuries to children — second- and third-degree abrasions, broken bones and lacerations. The CPSC’s own notice makes the point this article turns on: children may be seriously injured while the machine is being used by an adult, not only when a child has unsupervised access (CPSC, May 2021). By 2023 the reported totals had reached 351 pull-under incidents and 90 injuries (CPSC, 2023).

Separately, and relevant to anything selectorised: in June 2025 the CPSC announced a recall of 3,844,200 BowFlex 552 and 1090 adjustable dumbbells over weight plates dislodging from the handle, with 111 injuries reported (CPSC, June 2025). The successor model recommended below is not part of that recall — it is one of the remedies offered to owners of the recalled ones — but a plate leaving a handle mid-rep is exactly the event that matters most with a child on the floor beside you.

Two windows, not one

Every piece of kit has two hazard windows, and they are not the same size.

Read down the first column and you get the article everybody else writes: loose plates and a strap left hanging in a doorway are hazards while nobody is training, and both are fixed by putting them away.

Read down the second column and you get the one nobody writes. A kettlebell swing, a band under tension, a bike with moving pedals and a treadmill belt are all most dangerous at the moment you are busiest and least able to look around.

That is the window storage cannot touch. You cannot put away the thing you are using.

Why “put it up high” buys less than you think

The shelf is still worth having. It is just worth knowing exactly what it buys.

Standing, a four-year-old reaches somewhere near 48 in. On a chair they have moved themselves — and a child who wants something finds a chair — that becomes roughly 66 in, which clears a high shelf. A six-year-old on the same chair is at the top of a wardrobe.

So height is a delay, not a barrier. The variable that actually works is a door that closes, or a piece of kit small enough to leave the room entirely when you are done with it.

Which is a buying criterion, not a storage tip: it favours one object you can carry out over a set of loose parts you can only tidy up.

The three things this actually rules out

A strap left hanging in a doorway. A loop of webbing at toddler head height, permanently, is the single worst object on this page — and it is the one most people leave up because taking it down is a nuisance. If you buy a suspension trainer with a small child in the house, the rule is that it comes down every time. If you know you will not do that, buy something else.

Bands at eye level. A band that slips off a door anchor travels back at the height of a face, and a small person standing behind you is exactly where it goes. Bands are still on this page — they have no parked hazard at all — but the room has to be clear before there is tension in one.

Anything with an entrapment gap you cannot see into. That is the treadmill finding, and it generalises: if there is a moving part with a gap behind it, the gap is the hazard, and it does not care that you are the one using the machine.

The verdict

One object you can carry out of the room

BowFlex SelectTech 840 Kettlebell

Range

8–40 lb

Settings

6

Adjustment

Dial

Impact risk

Swings only

What we like

• +A single item: it leaves the room in one trip, which is the only reliable barrier
• +No loose plates, no collars, nothing that stays on the floor after a session
• +Nothing hangs, and nothing stores energy the way an elastic does
• +Sold and shipped by Amazon, so returns run through Amazon

What we don't

• −The dial is a pinch point, and 40 lb dropped on a small foot is 40 lb
• −Swings need a clear arc — the one movement here with an in-use hazard window
• −One bell will not load a household of two adults for long

The BowFlex SelectTech 840 kettlebell wins this page on a property that has nothing to do with training: it is one object, so putting it beyond a closed door is one trip and takes ten seconds. Every set of loose parts fails that test, and the thing that gets skipped when you are tired is the one that keeps a room safe.

If you want the reasoning on the bell against a pair of dumbbells on their own merits, that is a separate comparison.

There is a child in the room whenever you train

Buy the thing with the smallest in-use hazard and the shortest tidy-up. A single bell you press and carry, rather than swing, has almost no in-use window at all; bands in a cleared room are the other half of that.

You want proper load and there is a door you can shut

Then the constraint lifts and you are back to an ordinary purchase — buy the range. A lighter pair is genuinely easier to lift onto a shelf; a heavier one needs the door rather than the shelf, and a floor you have thought about.

The gym has to live in the living room permanently

Then rule out loose parts. A plate set is the cheapest load on this site and the worst possible choice here: collars, plates and a bar, all at floor level, all needing to be picked up one at a time. Buy fewer, larger objects even though it costs more per pound.

What breaks, and who fixes it

The failure that matters here is not wear. It is the plate that leaves a handle mid-rep, which is the hazard behind the 2025 recall of 3.8 million units of the previous BowFlex generation, and the reason what breaks on adjustable dumbbells is worth reading before you buy any selectorised weight to use around a child.

Practically: check the selector engages fully every single time before the weight leaves the floor, and do that with the child out of the arc rather than after they have wandered in.

Returns: the kettlebell, both selector pairs and the plate set are sold and shipped by Amazon. The band set is sold by WHATAFIT LLC and the suspension trainer by TRX Training — returns on those run through the seller.

Before you buy: five checks, thirty seconds each

1. Count the objects, not the pounds. How many trips does clearing the room take? One is a different product from six.
2. Find the moving part and look behind it. If there is a gap you cannot see into, that is the hazard, and it is live while you train.
3. Decide now whether the strap comes down every time. If the honest answer is no, do not buy a suspension trainer yet.
4. Measure your highest realistic shelf, then subtract 18 in for a chair. That is the real height you are working with.
5. Check the recall status of anything selectorised before you buy it, new or second-hand — used equipment is where recalled units keep circulating.

Questions people ask

Is a home gym safe with a toddler in the house? The parked kit is manageable with ordinary storage. The part that needs a plan is the time you spend training, because that is when the documented serious injuries to children have happened.

What is the most dangerous piece of home gym equipment for a child? On published incident data, a motorised treadmill — the CPSC recorded one child death and dozens of injuries from children being pulled under the rear of one model. In an ordinary free-weight setup, a strap left hanging in a doorway is the object we would remove first.

Is it enough to store weights up high? It buys time rather than safety. A four-year-old on a dining chair reaches roughly 66 in on our estimates, which clears most shelves. A door that closes is the barrier; height is a delay.

Are resistance bands safe around children? Parked, they are the safest thing on this page — they live in a drawer. Under tension they are the opposite, because a band that slips travels at face height. Clear the room first.

Should I buy second-hand to save money? Not anything selectorised, not with a child in the house, and not without checking the recall status first.

Sources and method. Treadmill incident figures are from the CPSC and Peloton recall notice of May 2021 and the CPSC’s 2023 update; the adjustable dumbbell recall figures are from the CPSC notice of June 2025. Product specs and sellers were read from the live listings between 28 August and 1 September 2026. The hazard-window classification and the child reach estimates are ours and are labelled as estimates — the reach figures exist to make a point about doors versus shelves, and are not anthropometric data. This site does not buy or use the equipment it ranks.

If you have had an incident with home gym equipment and a child, the CPSC takes reports at SaferProducts.gov — and tell us if a figure here does not match what you found.
