I pretty much worked out for myself that the problem was down to poor form but thanks for pointing that out.....
I think a physio would be more appropriate than a doctor in this situation and the massages would have to be done on a regular basis to provide any benefit unless they were a back adjustment massage.
The poor form wasn't down to having a lack of knowledge on form merely the muscular imbalance to maintain that form, so i don't think i'm going to sink as low as asking some un-qualified personal instructor (the ones at my gym anyway) and besides, i perform most of my workouts at home.
As for your second message: By new i meant not experienced, i have been doing it on and off for 3 years but now i am older i am going to do it properly.
Your point on not going under the 5RM is useful as it solidifies something that i was pondering myself.
As to why i was doing 1RM: honestly just to see how strong i was and mark my improvement. Now i have felt the ill effects of doing this on a weekly basis i will stop doing anything under 5RM or maybe 3RM's in a few months.
Thanks for the replies.
