Hey guys, I'm 17 and thinking about doing my first competition this summer in men's physique (teen obviously), but I don't know if I'm big enough. My arms are 15.5" (flexed, cold), my calves are very good, and my chest is okay (I think), but my back kinda sucks ass. I'm currently 5' 9.5", 168 lbs at 12-15% fat (scale says 12, but I think 15 is more realistic).
Do you think I'm big enough to do well, or should I put it off for a year or two and get bigger? The above pics are from a month or two ago, so I was maybe at 16-18% fat then.
