FITNESS: Catch the last free exercise program in the Wellness Wednesdays series from the National Park Service. This week’s concentration is on hiking and outdoor fitness equipment, and like the programs before it will take place at the Fort Dupont Activity Center (3600 F Street SE). 6-7 p.m. Free.

BOOK: All you single ladies (and dudes) probably know what a pain cooking for one can be. Joe Yonan, who used to write the Cooking for One column for The Washington Post, can help. His new book, Eat Your Vegetables: Bold Recipes for the Single Cook, is full of single servings, food buying tips, mock meat alternatives, and more for “vegetarian (or just vegetable-loving) cooks.” Learn more at his book event at Politics and Prose (5015 Connecticut Avenue NW) tonight. 7 p.m. Free.

VARIETY: The Wonderland Circus variety show brings comedians Andrew Bucket, Benjy Himmelfarb, and Pat Riley, as well as musician Jacob Panic and burlesque artist Karamel Sutra, to the Wonderland Ballroom (1101 Kenyon Street NW) this evening. 8:30 p.m. $5 suggested donation.

MUSIC: It’s been a year, and it’s still impossible to escape Carly Rae Jepsen. The Canadian pop singer turned viral sensation will be at Wolf Trap to promote one of my favorite records of last year, Kiss. Hot Chelle Rae will open. $30-42, 7 p.m. – Andy Hess
