I'm 17 and skinny, I've been doing pushups and tricep exercises for 3 years (only at home) and I have now started lifting heavy bags and buckets for a year.
After workout my right arm feels so strong and stiff and tight all the kind a strong arm feels also it looks bulkier. But the left arm still doesn't look bulkier or feel stiff, it feels too light.
During lifting the left arm also doesn't feel like being strained or overloaded.
Please tell me what should I do.
