You already walk every day. Put 4 to 40 lb on it and the same route asks more of your legs, hips and heart — no gym, no extra minutes, every pouch in the box.
Start here
Six 1 lb pouches in the box. Day one feels like a heavy sweater; ten pounds is a decision, not a second purchase. One adjustable size, over what you already wear.
Begin with the pouches out. Add a pouch when the last one stopped being noticeable — for most people every one to two weeks.
Add Light — $79 See LightA few pounds on your torso and every step costs a little more. Your heart works harder at the same pace; your legs, hips and back carry the difference. No gym, no class, no extra minute.
All 6 1 lb pouches are already in the waist band. Nothing to order, nothing to assemble.
Clip it on over your clothes. Two side buckles pull the band in to your frame; padded straps cross at the back. It shouldn't bounce — if it does, cinch again.
Day one: take the pouches out and walk at 4 lb. Slide one back in when the last one stopped being noticeable — for most people every one to two weeks.
The $28 vest is one fixed weight for life. Plate carriers are built for the gym and sell the plates separately. HEFT sits in between — adjustable, everything included, made to be worn on a Tuesday.

I have walked the same 45 minutes for years. Started at 4 lb, now at 8. Same route, and I actually feel my legs and back on the hill again. Sits low at the waist, nothing digging in.
It is a harness, not a garment — that was the part I didn’t get from the photos. Cinch the sides and it does not bounce. I keep it on the hook by the door and it is on me most mornings.
I was told to start carefully. Four pounds felt like a heavy sweater. I added a pouch every week or two and never had a sore day. Every pouch was in the box — nothing to order later.
My walks start before sunrise. Cars see me now. The weight band sits at the waist so my shoulders are fine after an hour. One star off because I wish it came in a second color.
Honest note: the first one I ordered was too much on day one because I loaded all six. Support told me to start at four. I did, and it has been on my body for five weeks now.
Bought Core for the stair loop at work. Twenty on day one was plenty, I am at 26 now. Straps are padded where it matters and the packs stay put when I run the last flight.
One adjustable size, black. Shoulder straps and side buckle straps adjust; it is a harness worn over your clothes, not a fitted garment. We don't publish a height range because we haven't measured one — if it doesn't fit, the 30-day walk test covers it.
