Pix, you're challenging yourself, getting well out of your comfort zone. That takes courage. You get my recognition for that. Entering into an environment , like a gymn, when confidence is low shows that you have that courage and more importantly a strong desire to achieve something. Remember, a load of the other people in there may have started on their journey some years or months ago and have some visible results for their efforts. visible results usually show in 3 months continuous effort. It usually takes about 12 weeks for very noticeable changes. By then, after 3 months, going to the gymn will be a normal routine for you. Stick with it, don't obsess over it, make it part of a lifestyle change. chip away at it, you'll see progress.
