Hi,
Interesting to hear someone else has a simililar problem to me!! I have been doing pump for about 2 years now. About 3 months ago I began to get a tingling/warm feeling in my hand about half way through squat track. At the time I was lifting 12kg each side, thought it may be too heavy, so reduced to 9/10, this did not stop the sensation! I have tried re positioning my grip etc but nothing seems to help. It stops as soon as I put the bar down! Very annoying.
I thought it may have been the bar compressing on a nerve or something, but after reading Micheal's post, it seems very plausible. I often do feel very tight around pec area, so will try this test tomorrow and let you know the outcome!! If there is a restriction I will get this worked on during my next deep tissue massage to see if it stops this limiting sensation!!!
