I've recently switched from BB Benching to DB Benching, and have a few questions...
1. DB Benching feels like I'm doing flies, as compared to BB Bench. Is this because when I lower the DB's, my hands are a bit wide apart, and when I press up, they end up coming together? I'm just not really sure on correct form with it because with BB your hands stay the same width apart the whole time. How should I do them if I want to be able to press the most weight possible? I suppose I try to keep my hands wider apart during the press upward, but they just naturally close in for some reason.
2. I lower the DB's until I feel a pretty deep stretch in my pecs, virtually as low as I can go. I could probably go a tad bit further but the RoM feels very full to me. Should I not go so low as to stretch the pecs? Is that dangerous?
3. My shoulders (especially my right one for some reason) tend to feel a bit shakey during the exercise. Is this simply an effect of recently switching over from BB? Stabilizers and what not?
4. When setting up, I bring the dumbbells up and rest them on my quads, with my grip in hammer position. Then I sort of just fall backward while keeping the DB's tight, proceed to set up my arch and then press. It feels a bit weird just having my back sorta slam down onto the bench. Is there a better way of doing this?
