OK. One thing that was mentioned multiple times in the comments was along the lines of I'm too fat and/or not good/strong enough to try yoga. I'm going to tell you a short version of my life story, and hopefully it will change some of your opinions on what you need to look like to go to the gym.
Childhood years: Mom send me to Weight Watchers when I was 12. I was a national level swimmer, working out 2 -4 hours a day, and my calorie intakes was at about 1200 cals a day. (that is insanely low, for those of you that aren't obsessed with weight). If my mom left me home alone? I would cook myself rice or pasta because I was SO hungry. I really think she was doing what she felt was best, as she was chubby in high school and got called Hippo Hips (kids are awesome, no?). Even with all this work, I was still about a size 12 - 14.
College: First time I was really allowed to eat whatever I wanted. But was still swimming (and now that I was in college, was working out 5 -6 hours a day with the swim team). I didn't gain much weight, but was a size 14 - 16.
Out of college: Worked a consulting firm about 90 - 100 hours a week for 2 straight years. Gained weight, stopped working out, and was up to a size 16 - 18.
Shitty 3 month period: I fell in love with a bad man. I realized my mistake and left him. He stalked me and threatened to kill me. I lost 60 pounds. My mom wouldn't stop taking pictures of me. Got down to a size 12.
Move to Boston area: Got a new job, was working out regularly, did gain back about 50 pounds, but was doing triathlons. Even completed an Ironman. Was about a size 16 - 18.
Got Married: Now living the American Dream. Got good job, got married, bought a house....didn't get pregnant. Got sad. Stopped working out. Gained weight. Weighed more than I ever have. Up to a size 24!
Got ass in gear: I forced myself to go to the gym. This was really hard. I felt I was too fat. I felt that people would stare. It was the exact opposite. I started doing power yoga, and the people there were so supportive. And I started walking. I could barely make it a mile. My lower back hurt when I walked because I had spend so much time on my ass, my back muscles were THAT WEAK. I slowly walked more. And went to yoga more (at the most, 3 times a week). I felt great. I lost 25 pounds, I did the Breast Cancer Three day (and I walked every single one of those 60 miles), and felt wonderful again. Down to a size 22 (a loose 22 - the 24s were actually TIGHT before)
Last year: Had the ectopic. Gained back 10 pounds. Had doc tell me a needed to lose 20 pounds to get to do IVF. Ass gets kicked back in gear. Now, I'm down 33 pounds from when I started losing weight last April, and am wearing a loose size 20.
So - as you can see, it's been a lifetime struggle. I'm still the fat girl in the yoga class. And I don't care. I look this way, but I am strong. And I have been even bigger, have been very weak! Stepping into that yoga class for the first time 15 months ago was tough, I'll admit it. But I forced myself to do it, and it was one of the best things I've done for myself in a while. We are all at different point in our life and our fitness journey's. No one is judging you! (or if they are, they are assholes). If you go to the gym, and you don't like to see what you look like in workout clothes - don't look in the mirror! I don't have full length mirrors at my house for this exact reason. In yoga class, if the room has a mirror - stare at yourself in the eyes. That is what I do. It not only makes to stop obsessing about the flab on your belly, but helps in the balancing postures.
OK - I'm off my soapbox now. Here is my progress for the week:
Yoga: 4 times
Walked: 6 times (4 three mile walks, two 6.5 mile walks)
Weight: stayed the same (so still .5 pounds to go - but I wasn't as careful with my sodium this week - so I'm really happy I maintained 4 pound weight loss from last week!)
