I've been a full-time office worker for such a long time without doing any exercise so I'm very new to lifting and weight training. When looking up advice and programs to get me started- like the very helpful getting started a section in this sub- almost all insist on standard progressive barbell training like bench presses and barbell overhead presses. In my understanding, though, dumbbells allow for a greater range of movement and recruit more muscles for stability. I realize you can lift much more weight doing barbell versions of exercises, but is this really necessary for someone like me who cares absolutely zero about how much weight I can bench press and am working out solely to build muscle and improve my physical appearance? Can I just substitute barbell exercises for dumbbell exercises? Will this actually limit my progress? Thanks!
