I've mentioned shoulder and pain and squatting here on the blog numerous times but, for whatever reason, I've neglected this nice little modification that makes holding onto the bar a little less challenging for those with mobility issues. Using a combination of the Manta Ray and lifting straps will take some stress off of the shoulder girdle and allow the lifter to focus on squatting.
For those lifters who are trying to work their way back to barbell back squatting, a combination of grips with and without the straps and with and without the Manta Ray, can be experimented with.
