I watched this vid and made me think that I should commit to Sumo for a while and see what happens.
He makes the points that independent of body type (arm/torso lengths, etc) sumo has better leverages and is more reliant on the legs rather than the small and easily over-taxed lower back muscles.
I am guessing that most start with conventional b/c it's a seemingly more straightforward, easily learned movement, but it seems that sumo may be a better lift in the long run b/c of its emphasis on larger muscle groups?
Anyway, tips for making the switch? When did you do it? I'm still making notable newbie-gains on conventional so maybe let it roll for a while? Do sumos as assistance for a bit first?
