Straddle running man strange sensation

Hi

Anyone come across this before?

Towards the end of a Straddle running man set I get a strange sensation in the traps and scapulas. It's not painful and goes within a couple of seconds after stopping without any lasting effect but feels really uncomfortable at the time. Just wondered if this was normal? or is this a body response from doing more reps than i should be?

Thanks in advance 

Are you depressing the scapulae?

Possibly, I would have to have a go tonight to make sure though.

I took this tonight. Just wondering if you notice any issues from it. 

Thanks again

Your traps actually work a lot in order to stabilize the twisting of the spine, you are lifting the legs by far more than hips height and this is the mistake.

I didn't know this. It would explain a lot though. Good info, thanks Alessandro
