Couple basic lifting issues I'm wondering about lately: Elbow position during incline DB press If you keep your elbows tucked in close to your chest, as opposed to away (with upper arms nearly perpendicular to chest), does it affect involvement of pec and/or front delts? Use of abs during lifts In general, when lifting (especially heavy, or on squats/leg presses, etc.) are we wanting to "suck in" our abs while tightening them during the lift? I have noticed an... expansion... of my lower abs recently. I particularly notice it during it when doing a leg press on my smith machine (on my back, legs vertical & pressing upward). Thanks in advance!
