Is it better to focus on form, than it is on the amount of weight. Last night when I lifted I decided that I would concentrate fully on form and contraction, rather than using a big ass a mount of weight. I feel more sore, and felt a lot better when I lifted. Like when I usually weight I use for lat pulls, I rock and don't fully touch my chest. I went down aout 50 lbs. and touched my chest and held and work the lats a lot better. Which is better? amount of weight or form?
