Throughout Mark Bell's career, he has suffered multiple shoulder injuries due to heavy bench press training. Being one of the strongest bench pressers in the world, Mark could not just sit out and skip bench pressing due to shoulder pain. He wanted to continue to bench heavy without the pain while reinforcing proper form, so he created the Original Sling Shot®.

The Maddog Sling Shot® is double ply and twice as thick as the Original Sling Shot®. The Maddog’s increased tension makes it perfect for lifters working with weights over 400 lbs. Its dramatic support allows you to handle significantly more than your max, training the nervous system and preparing you for your next PR.

The Maddog Sling Shot hardcore design was inspired by Mark Bell’s brother Maddog Mike. Built to support the strongest benchers, the Maddog was designed with input from multiple world record holders and professional athletes resulting in a Sling Shot with unparalleled performance.


How do I know if the MadDog is right for me?

The MadDog is best for weights over 415 lbs. We do not recommend purchasing this product if you have not yet reached that weight yet on your bench. The MadDog is designed with material double the Original Sling Shot® and may compromise your form if you bench with weight less than 415 lbs.

Does the size chart fit both men and women?

Yes! We go off of body weight, doesn't matter who you are 🙂.

How do I know which Sling Shot® is best for me?

You can decide which Sling Shot® is best for you according to your raw one rep max. You can select the size based on your body weight in pounds and if you're really tall (over 6'4" we recommend you size up).

According to the size chart I am a 2XL but I used my friends at the gym and his XL fit me just fine, which one should I go with?

We recommend going with the recommended size chart. It is unsafe to have a Sling Shot® that is too small. If you're not sure if your Sling Shot® is too tight, put your Sling Shot® on then put your hands to the side. If the cuff's seam brings your arms in closer to your body, it is too small.

My Sling Shot® came with a logo different than the ones I see on YouTube, do I have a genuine Sling Shot®?

Yes! We have updated our Sling Shot® to have a white web in the center of the product. You have our latest edition of the Sling Shot®! If you want to double check feel free to email us a picture of your Sling Shot® with your proof of purchase to

I purchased my size according to your size chart but it's loose on my arms, should I return for a smaller size?

We do not recommend you sizing down because of how the cuffs fit. What's important is where the cuff and the center band seam aligns with the crease of your armpit. It's okay if the Sling Shot® feel loose on your elbow/bicep.
