You want to look good in skinny jeans, but you’d settle for not scowling in front of three-way mirrors.

Change your rear view and then some with the monthlong Lift series by Cara Weaver.

Starting March 17, the health and fitness professional, Nike trainer, and Flywheel instructor (who also happens to be our body idol) is leading a twice-weekly 60-minute workout that incorporates weights, squats, lunges, and serious core strengthening. Weaver ensures your form is flawless, for optimal results, fewer old-lady pains, and long-term fitness success.

In addition to the eight sessions, you’ll sweat again at a bonus Fast Twitch class (Atlanta’s notorious ass kicker) and get swimsuit shopping tips from fashion expert Lillian Charles. Other perks: a membership to The Forum for the month and a healthy-eating seminar, including meal-planning tips to tidy up your diet.

Squeeze it all in.

Lift series at The Forum Athletic Club, Lenox Square, 3393 Peachtree Road Northeast, suite 2010, Buckhead (678-904-1940 or theforumathleticclub.com), $175.
