What's the advantage of the Z-Fit™ vest over the sand-filled one?
The Z-Fit™ vest won't shift like sand, so the weight stays evenly distributed. It's more portable and much more comfortable to wear.
How does using a weighted vest improve my workout?
Wearing a weighted vest adds resistance to boost your strength and endurance, while improving posture and maximizing workout results.
Any tips for beginners using a weighted vest?
Start with a lighter weight to get your body used to the added resistance. Pay attention to your body's signals, and don't push yourself too hard in the beginning.
No problems with it perfect and it was as described. I use it when I go to the gym it’s good for walks or jogs
I bought your 5, 10, and 15 pound weighted vests so I could ease into heavier weights. I'm doing the 5 now and will switch to the 10 next week. I'm not a small gal so I was worried it wouldn't fit me well, but to my surprise it fits comfortably.
I was so surprised feel great and looking forward to useing it every morning! Thank you
I absolutely love this vest it has been a game changer for my walks. I get a full body work out as if I am using weights as I walk.
I love this product so much I now have a 10 lb vest and 15 lb vest. Great investment for my health.
