ATXfitness

Black Swan Yoga is my very, very favorite place to exercise in the city. They have 4 locations, awesome teachers & it is donation based! The one on Westgate is right near my house. I would go everyday if my schedule permitted. http://www.blackswanyoga.com/
Also, follow them on Facebook & Instagram for some funny & insightful posts.

If you want your ass thoroughly handed to you in a work out, this is the place for you! A cool thing about Synergy Fitness is that while they have two indoor HIT centers, they also offer boot camps throughout the city in some of Austin's beautiful parks. You can buy monthly packages, 6 month packages, or $15 drop ins. I once did 100 burpees total in the span of one of their 60 minute classes. Also, all the trainers are insanely nice & helpful. http://www.synergyfitnessbootcamp.com/

With 4 different locations in Austin, Planet Fitness is a great gym for someone on a budget. They have plans starting as low as $10 a month. They are able to keep it so cheap because there aren't a lot of bells & whistles. No classes, day care, pools, full time trainers, etc... But for the money, it's a great gym! I was a member at PF for nearly 3 years. I only switched because I do love going to group classes. But if that's not a selling point for you- I cannot say enough nice things about PF & their budget-friendly approach to fitness. http://www.planetfitness.com/‎

I have never been to a place quite like CG Arena. The CG stands for Camp Gladiator, and as the name implies, they go hard. Go check out their webiste. You'll notice that budget isn't exactly on their minds, but if you can make it work, I highly recommend it. Their studio is top of the line & their instructors push you hard.

Do you love shaking your thang? Are you on a budget? Do you live on the south east end? Then this little bitty Zumba studio may be right up your alley! Corazon: http://www.corazonz.com/index.html

These guys don't eff around and they're vegan to boost. http://www.beyondfitaustin.com/
