Note to self: stop making stupid resolutions that you always regret. January is bad enough.

But if you must, you may as well have fun while you detox at the Disco Health Club.

At the weekly ’80s-style aerobics class, which launches tonight, you’ll learn dance combinations inspired by Jane Fonda and Olivia Newton-John. There are lasers and lights (very clubtastic) as well as a bar serving water, juice and smoothies and a DJ spinning classics from the likes of Michael Jackson, Cyndi Lauper, and Wham.

You’re encouraged to dress the part, so break out the shiny leggings, legwarmers and retro sweatbands — or just go crazy at American Apparel. At 10 p.m., the venue opens as a proper disco. The perfect opportunity to show off your new moves.

Drinking, dancing and cringy outfits.

Maybe the healthy life isn’t so different after all.

Available at The Green Carnation, 5 Greek Street, W1D 4DD (020 7434 3323). Tickets online at wegottickets.com.
