I haven't lifted for a year and a half but started back about a month and a half ago lifting again. My strength has dropped alot but everytime i bench with dumbbells my arm shakes, last week it was my left arm, and this week its my right arm. These are with weights that i can push up fairly easily but my arm shakes and makes it harder to stabilize the weights. One of the guys i worked out with told me he thinks theres something up with my stabilizer muscles. Anyone have any idea? Anything i can do to fix this? Its been happening since i've started working out again, month and a half.
I'm in a calorie deficit right now trying to lose weight, 1500-2000 calories a day.
