FAQs
Please read our FAQs page to find out more.
What makes Hardbody products different from other lifting equipment?
Hardbody is designed by lifters, for lifters. Every product is tested in real training environments to balance comfort, durability, and performance, not just looks.
How do I break in my new Hardbody belt?
Like any high-quality lifting belt, it may feel stiff at first. The best way to break it in is simply by training with it. Over time, the leather will mould to your body and become more comfortable while maintaining maximum support. You can also fold the belt gently in both directions to help loosen the leather for a better fit.
How do I choose the right size belt or sleeve?
Each product page has a sizing guide with measurement instructions. Use a tape measure, not your jeans size, that’s the number one mistake most lifters make.
Do your products come with a warranty?
Yes. All Hardbody products are covered by our Lifetime Warranty against manufacturing defects. If your gear fails when it shouldn’t, we’ll replace it.
How do I claim the Lifetime Warranty?
Contact our support team with your order number, photos, and details of the issue. We’ll review and arrange your replacement. You can find full details on our Lifetime Warranty page.
If you have any questions, you are always welcome to contact us. We'll get back to you as soon as possible, within 24 hours on weekdays.
