How to Ruck With a Regular Backpack: What to Use for Weight

The gear is not the barrier

Rucking has picked up a lot of specialized equipment in the last few years: molded plates, purpose-built packs, branded everything. It's easy to come away thinking there's a purchase standing between you and your first session.

There isn't. Rucking is walking with weight. The backpack in your closet and a few things already in your house will get you through your first month, and by the end of it you'll actually know what you'd want from better gear. That's a better position to buy from than guessing on day one.

What does matter is how the load sits. A stable twenty pounds in an old school bag will teach you more than a shifting twenty pounds in an expensive one.

Check whether your backpack is up to it

Most daypacks handle a modest load fine. A few things are worth a quick look before you put weight in one:

• Shoulder straps with some padding and width. Thin cord-style straps concentrate pressure and will find your collarbone within a mile.
• Stitching at the strap anchors. This is where a loaded pack fails first. Give the seams where the straps meet the body a firm tug.
• A sternum strap, if it has one. It keeps the straps from sliding outward, which is most of what makes a light pack feel unstable.
• A back panel that isn't completely floppy. Some structure helps the load stay put.

School bags, work packs, and old hiking daypacks usually pass. Drawstring gym sacks and single-strap slings don't, and it isn't close. Neither distributes load across both shoulders in a way that survives a few miles.

A hip belt is genuinely useful once loads get heavier, and its absence is the most common reason people upgrade. For a light start, you can do without.

What to use for weight

The requirement is simple: dense, stable, and not sharp. Anything that meets those three works.

Water. A gallon jug weighs about 8.3 pounds (3.8 kg), and a liter of water weighs about 2.2 pounds (1 kg). Water is free, easy to adjust, and can be poured out if the session goes badly. The catch is that it sloshes, so fill containers completely to remove air, and double-bag anything going near a phone.

Bags of rice, flour, beans, or sand. Five and ten pound bags are dense, they conform to the shape of the pack, and they sit quietly against your back. Put them inside a second bag or a packing cube so a split seam doesn't end your walk.

Bricks or pavers. A standard brick runs about 4 to 5 pounds, they cost almost nothing at a hardware store, and two or three gets most beginners into a sensible range. Wrap each one in a towel or an old shirt and tape it. Unwrapped brick against a pack's back panel is uncomfortable within minutes and hard on the fabric.

Dumbbells or weight plates. If you already own them, they're the most compact option. Wrap them so they can't shift and so the metal isn't riding directly on your spine. A 25 pound plate fits most daypacks; a 45 usually doesn't.

Bags of pet food, cat litter, or sand. These come in convenient marked weights, which makes them easy to log accurately.

Books. They work, though they take up more room per pound than anything else on this list. Fine for lighter loads, awkward past fifteen pounds or so.

Whatever you choose, weigh it. Guessing at your load makes every session after it harder to compare, and a bathroom scale with and without the pack takes ten seconds.

Packing it so it rides well

This part matters more than what you put in the bag. The same weight can feel completely different depending on where it sits.

Keep the load high and close to your back, roughly between your shoulder blades. Weight that rides low pulls the pack away from your body and drags your shoulders back, which is where most posture problems start.

Build a platform first. Put a rolled towel or a folded sweatshirt in the bottom of the pack, set the weight on top of it against the back panel, then pack more soft material around and above so nothing can move. When you're done, hold the pack by the top handle and shake it. If you hear or feel anything shifting, add more padding.

Then tighten the straps so the pack sits snug against your back rather than swinging behind you. Clip the sternum strap. You want the pack to move with you, not a half-beat after you.

How much to start with

For most beginners, somewhere in the range of 10 to 20 pounds (about 4.5 to 9 kg) is a reasonable place to test, which lands near 10 to 15% of body weight for many people. Starting lighter is completely valid if you're newer to exercise or returning after time away.

Improvised weight has one small advantage here: it's easy to adjust. Pour out half a jug, take a brick out, add a bag of rice. You can find your range in a couple of sessions instead of committing to whatever plate size you bought.

Use the ruck weight calculator for a starting range, and read how much weight should I ruck with for how to decide whether to add, hold, or reduce after the first few walks.

When it's worth buying real gear

There's no rule that says you have to. Plenty of people ruck for years with a normal pack. But a few signals suggest an upgrade would actually solve something:

• Your loads are past roughly 30 pounds and the shoulder straps are the limiting factor
• You want a hip belt to move weight onto your hips on longer sessions
• Your improvised weight won't stop shifting no matter how you pack it
• You're rucking often enough that packing the bag has become a chore

Those are real problems that better equipment fixes. "Everyone online has one" is not. The beginner rucking checklist covers what's genuinely worth having early, footwear included, which matters considerably more than the pack does.

Frequently asked questions

Can I use a school backpack for rucking?

Usually yes, for light to moderate loads. Check the shoulder straps and the stitching where they attach to the body, since that's the failure point. Keep the weight high and padded, and avoid it entirely for heavy loads.

Is a ruck plate worth it?

It's convenient rather than necessary. A plate is flat, dense, and sits against your back without shifting, which removes the packing problem entirely. It does nothing for you physiologically that a wrapped brick of the same weight doesn't. Buy one if you're tired of packing improvised weight, not because you think it trains you differently.

Does the backpack itself count toward the weight?

Count everything you carry: the pack, the weight, and your water. Weigh the whole loaded bag on a bathroom scale. Water is worth noticing because it gets lighter as you drink it, so a session can end a few pounds lighter than it started.

Can I ruck with a weighted vest instead?

You can, and it's a reasonable option for shorter sessions. A pack generally suits longer distances better because it carries the load higher, adjusts in smaller increments, and can hold water and layers. A vest sits closer to your center of mass, which some people prefer for stairs or mixed workouts.

What's the safest household item to use?

Bags of rice or flour, wrapped and secured. They're dense, they conform to the pack, they won't leak into your electronics, and they come in known weights so your log stays accurate.
