trying to find people with common goals or workout tips!

Hey guys! I am 18 years old, 5'5, and 125 pounds! I recently lost about ten pounds, and now I wanna lose another inch off my waist, thighs, and arms, and get some lean muscle! I am not really trying to lose lots of weight, because I know muscle weighs more than fat so if I gain muscle I will probably gain a few pounds!

Anybody out there sortof in the same boat as me? Or anyone up for giving me some pointers? I am good in the food area (I eat really well), but I just have a few questions about proper form and tips on workout routines! I wanna make sure I'm getting the most out of my workout, so I can make get out of my comfort zone and make a difference with my body!
