“I’ve owned this attachment for quite a while and although it only comprises a small percentage of the total number of exercises I do, it’s effect and efficiency can’t be replicated with anything else.” – Jonathan B.

Exercise with the Ironmaster Hypercore Attachment

IronmasterUK Lower Back


A great exercise for your lower back. Slot the Hypercore Attachment into the Super Bench set in the flat position and adjust the foot holder so your upper quads lie flat on the pads and you can bend at the waist. Straighten your body and cross your arms in front of you (or hold a weight plate if you want extra resistance). Keep your back flat, and slowly bend forward at the waist until your hamstrings feel stretched and you can no longer keep going without rounding your back.
Return to the starting position slowly and repeat. Make sure your starting position is not past a straight line and do not swing your torso.

IronmasterUK Abdominals

Oblique crunches

Set up the Hypercore Attachment as above. Lie sideways on the attachment with one foot on each foot rest and your arms behind your head. Starting with your body in a straight line, lean sideways towards your hip that sits furthest from the bench. Return to the straight body position and repeat.

IronmasterUK Abdominals

Roman chair sit ups

Work the abs by performing forward facing sit ups on the Hypercore Attachment. Set up the attachment as above, and position yourself facing forward. Complete a sit up with your arms crossed (or holding a weight plate if you want extra resistance). Slowly return to the starting position and repeat.

“This takes up very little space without sacrificing quality and functionality. Because of Ironmaster attachments like this it’s no wonder why I’m fully sold on the Ironmaster ecosystem.” – Mark N.

Hyper Core Attachment

1 review for Hyper Core Attachment

  1. I have just received the hyper core attachment today so thought I would do a review as no one seems to have done one yet which I’m surprised at. I wrecked my back doing deadlifts a few years back and my back has never been the same since. I decided to purchase this attachment to add hyper extensions to try and rehab my lower back and build up slowly. Weighted hyper extensions will replace deadlifts going forward.

    First of all the build quality of this attachment is as you would expect from IronMaster, first class and wants to be for the price. Every piece was in top condition no paint work scratched all the screws were there etc. Putting the attachment together was a breeze and its fits in the bench effortlessly.

    Stability wise, it doesn’t budge I’m 6’4″ and weigh 240ibs and its held my frame perfectly. I was using the attachment for the second last hole so would say this would fit someone up to about 6’8″ without a problem. I belted out 3 sets of 10 hyper extensions as a test and It’s really comfortable to use. The gap between the pads make it really comfortable for a man as your junk goes between the pads rather than getting crushed like on most gym benches I’ve used in the past.

    Over all Im really happy with this purchase and know that this will last a lifetime for me (as the sole user) as with all the attachments and the bench itself. Great work once again!!!
