I'm wondering if I'm alone in this. I always feel that it's much harder to get a good squeeze and, therefore, a good workout when I'm doing "pulling" exercises. As a result, I think my back, biceps, hamstrings, etc. suffer because of it. It just seems that squeezing is so much easier with "pushing" exercises...back, tri's, quad's, etc...and I gain here more quickly. Any tips?
