Not supposed to squat today but had a play with some wider stance work. It shows potential but it'll take a lot of work to get my groove corrected.
This is 240, not bad for a first try with new stance.
When you've got to go, you've got to go, I guess.

Serious work! Well done!

Hi guys - just started working out a bit and following the beginners guide.
One issue I find is doing bent over dumbbell rows - I feel like I use too much arm and not enough back muscle. The things I try to do is use my hand as a hook rather than gripping tight (to stop so much forearm/bicep work) and think about the backs of my elbows being pulled up. Anything else I should be doing to isolate back muscles?
Pull your elbow, yes, but are you pulling it back to your waist? Also, if the weightis too light, a lot of people are tempted to stabilise the angle of travel of the dumbell (I.e. Maintain a certain position with it) using muscles of the arm.
Finally, it is also difficult to get the lats to feel like they have actually done anything from my experience: they often just die quietly whilst the arms muscles are a bunch of attention-seekers.
