Best workout in a Victorian

Healthy Habits Studio turns 21 this year. Housed in an old Victorian on J and 23rd streets, the classes here are often filled with the fit and beautiful, but it doesn't mean the instructors aren't also kind to fat, klutzy Groupon-using visitors. I imagine that they would be nice to all. The trainers turn boot camp fitness classes into chatty sessions—probably with the intention of keeping your mind off the immense pain in your body. The conversation veers from what people ate that they shouldn't have (boring) to comics and ninjas (exciting!). They are all modern, too; you can reserve your spot in classes online. 2224 J Street, (916) 444-7729, www.healthyhabitsstudio.com. G.G.
