"I was setting my alarm at 5AM just to work out in secret."

Now my 3-year-old ASKS me when it's gym time. No more guilt. Just us lifting together.

Frequently Asked Questions

Everything parents ask before buying — answered honestly.

Safety & Development

No. This is the most common myth in children's fitness — and it's been debunked by every major medical authority. The American Academy of Pediatrics, the Mayo Clinic, and the International Sports Sciences Association all confirm that age-appropriate, lightweight resistance play has no negative effect on growth plates. Little Lifters start empty and weigh less than most things your toddler already carries around the house. You're not putting your child under a barbell — you're giving them a fun toy that happens to build healthy movement patterns.
Yes. Little Lifters are designed specifically for children as young as 12 months. There are no small parts, no hard metal edges, and no fixed heavy weight. You decide exactly how heavy the set is by controlling how much water you add. Empty, it's lighter than a sippy cup. The entire set is BPA-free and non-toxic — because we know your toddler is going to put it in their mouth before they ever try to curl it.
The opposite. Lightweight resistance is exactly how professionals introduce movement to young children. And here's what surprised us during our research — kids who watch their parents exercise already absorb way more than you'd think. They mimic your squat form, your press, your deadlift. The 20-exercise play guide included with every set turns those natural imitation instincts into proper, age-appropriate movements. Think of it as form practice disguised as a game.
Yes — and there's real science behind it. Occupational therapists call it "heavy work": lifting, carrying, and pushing weighted objects provides proprioceptive input that calms the nervous system. It's not just about tiring them out — it's about regulating them. Parents who've tried every trampoline and climbing dome tell us Little Lifters is the first thing that makes their child calm, not just crashed.
Outdoor play is wonderful — but the AAP reports that only 1 in 4 children get enough daily physical activity. And here's the reality: you can't go outside every day. Rain, winter, nap schedules, sick days. Little Lifters works indoors, year-round, in 10 minutes, with zero setup. It's not a replacement for the playground — it's what happens when the playground isn't an option.
So do we. Little Lifters isn't a training program — it's a toy that lets your child do what they already want to do: be like you. No child picks up a Little Lifters barbell because they're worried about their health. They pick it up because mommy or daddy just picked up theirs. You're not pushing anything. You're letting them in.

Age & Sizing

Not at all. At 12 months, your child won't be doing bicep curls — they'll be holding it, carrying it around, banging it on the floor, and feeling proud of themselves. That's exactly what they should be doing. The water-fill system means this same set still works when they're 3 and copying your squats, or 5 and doing full "workouts" with you. You're not buying a toy for one age — you're buying one that lasts through every stage.
Fill the weights to maximum and it still offers a real challenge for older kids. Little Lifters is designed primarily for ages 1–6, but plenty of 7-year-olds love having their own gym equipment. If your child is already into organized sports or serious training, they may be ready for the next level — but for home play with mom or dad, this still works great.
Strength, confidence, and wanting to be like mom or dad have nothing to do with gender. The design is bright, fun, and made for every child.
Not at all. You don't need a home gym or a CrossFit membership. If your child has ever grabbed your water bottle and pretended it was a dumbbell, copied your movements during a YouTube workout, or just said "I want to be strong like you" — this is for them. The set works in a living room, a bedroom, a backyard. No gym required.

vs. The Competition

This is what happens with cheap, fixed-weight plastic dumbbells — and it's exactly the problem we solved. Static toys get boring because the child outgrows them in weeks. With Little Lifters, you add more water as your child gets stronger, so the challenge keeps evolving. Parents consistently tell us their kids ask to "do their workout" every single day for months. The secret is that the toy never stays the same — and neither does your child.
Because you'll end up buying three of them. Those $10 sets are fixed-weight plastic that breaks the first time your child drops it — and your child will drop it. Amazon reviews are full of cracked plates, pieces falling off, and toys that last a week. Little Lifters is water-fillable, adjustable, and built to handle real play. One set that lasts years versus a cheap one you replace every few months. You do the math.
WOD Toys made the category popular — credit to them. But they're fixed-weight plastic at $40–50, and reviews consistently say two things: "not worth the price for what it is" and "plates cracked when my kid dropped it on the floor." Little Lifters gives you adjustable water-fill weight, a kettlebell, and a 20-exercise play guide. Different product, different philosophy.

Product Details

This is the #1 complaint on every cheap water-fill product on Amazon — we've read every single one of those reviews. Leaking was the problem we were most obsessed with solving. Our sealing system is designed to stay tight through drops, shaking, rolling, and throwing. Fill it, close it, and don't think about it again.
We recommend water only. It's easy to pour, easy to adjust, and if a cap ever comes loose during play, you're cleaning up water — not sand ground into your carpet.
The barbell bar, water-fillable weight plates, a kettlebell, and a 20-exercise play guide full of games to do together. Everything your little lifter needs from day one.
Fully BPA-free, non-toxic materials. Designed for children who will chew it, throw it, sit on it, drop it from the couch, and use it as a drumstick before they ever use it as a weight.

Exercise Guide

Parent-child movements turned into games — squats, curls, overhead presses, farmer walks, deadlifts, and more. Each one is designed so your child thinks they're playing while you know they're building coordination, strength, and confidence. The guide includes age-based suggestions so you always know where to start.

I was worried about them dropping these on their toes, but empty they are light, and full of water they are just heavy enough without being dangerous.

The product is great, but the shipping box was a little dented upon arrival. The weights were fine though.
