Me again - still having problems with my sumo.

As advised I've been running them as my speed work and they seem to be coming on well. So I thought I'd try again and this time in my sumo suit.

It seems when the weight gets heavy I pull it towards my right leg and it stops it moving.

Here's a short vid -


Sadly didn't get any videos of the ones a made 10lbs lighter. The thing that gets me is this doens't feel heavy TBH.

So, any help much appreciated guys
