well I just got my job back at Sonic. I do my paperwork Wednesday. after I get my first pay check I get to finally get my gym membership and start working out. but ive always been naturally skinny. I've never liked working out because I'm super self conscious and I feel like if somebody is looking at me they are judging me. but I like working out when nobody is looking if that makes sense but I have another mommy friend who is gonna be my work out buddy so I'll feel better. but what should I wear to work out. whats the most comfortable thing that wont make me feel gross while I'm still chunky?
