Jan Free I'm having a lot of trouble signing into the app, so once I can, I will be able to rate the corefirst with more experience. I will say the guys have been very responsive and nice, but so far, there is an issue and it's taking a lot of my time with no results.

Amy Adelman The CoreFirst Slider Disks are the perfect accessory to the CoreFIrst System. I was impressed with the size and functionality, They are double sided to allow a smooth slide on carpet or hardwood! I also love that course on the app utilize them! Adds a variety of new exercises. Very happy with this purchase!
