Been playing with sumo as an accessory. Still using my back thou, not all anterior. Feels good on my hams and I get a nice stretch, I get this weird itching or got feeling in my right ham and hope that's not how a tear starts out. I'm actually much weaker at sumo, so I assume getting it higher should help somewhere?
On a side note, deadlift bars do not give more do they? My friend claimed they do, to make the lift easier. I thought that was Only Olympic bars to avoid the shock. I used a bar with a lot of give the other day and I was actually weaker because I'm used to pulling out of the bottom. I was under the impression they were stiffer.
Glad to hear you're implementing some sumo. Idk about that itchy hot feeling man, I've been fortunate enough to not experience any tears thus far. Just keep an eye on it, if it gets worse get it checked out. Getting your sumo numbers up will definitely help your conventional pull as well as your squat.
Yes, there actually is a difference between a pull bar and a regular bar.. first being the diameter(slightly smaller) and the knurling being more aggressive. Secondly, it will give more. This allows you to get your shoulders back and chest out (removing the slack).
