Become a zoo animal, play beach volleyball on a trampoline or bowl in the dark—here are five activities that actually make working out fun.

Zuu at Virgin Active

Zuu

Tap into your primal instincts at a 20-minute full-body workout which incorporates movements inspired by animals. Channeling your inner beast may sound a little loopy here, but this class is more than just about grunts and growls. Zuu is a high intensity interval exercise which uses six different moves—push, pull, bend, twist, squat, lunge and locomotion—each named after an animal inspiration in a session that purports to burn an average of 300 calories, while helping you improve your mobility, agility, flexibility and cardio endurance. Virgin Active Singapore, #06-00 1 Raffles Place Tower 2, 6908-7878.  

Bossaball

Infusing volleyball, gymnastics, soccer and capoeira, kick, spike or dive on an inflatable court flanked by trampolines. While it might seem like child's play, this team sport is far from just playing ball on a bouncy castle. It combines agility, game strategies and techniques with the challenge of manoeuvring a gravity-defying playing ground, all set to samba or bossa nova tunes. For information on upcoming sessions, visit Bossaball Singapore. #02-08 10 Raeburn Park, 6100-6292.

Automated Indoor Baseball

This undoubtedly classic American sport has finally made its way to soccer-loving Singapore. At Homerun Baseball, you get to touch base not on a dusty pitch, but inside an indoor baseball batting cage instead. The premise is simple: all you have to do is to arm yourself with a bat and fend off a series of balls shot at you by an automated batting system. And this sport isn't just about working off some post-work rage—apparently you can burn between 200 and 300 calories an hour while working the core, arms and shoulders. 200 Pandan Gardens, 6635-6315.

Cosmic Bowling

Bowling isn't exactly the sexiest sport right now. But throw in pulsating beats, glow-in-the-dark pins and an atmospheric club-like setting, and it may be marginally cool. If you'd like a bit of kitschy and competitive fun, then gather your friends and head down to Orchid Bowl, where bowling alleys stay open till 1am from Sun-Thu and 3am on Fridays, Saturdays and eve of public holidays. It's currently available at The Chevrons (#04-01 48 Boon Lay Way,6795-5900), SAFRA Tampines (#03-01 1A Tampines St. 92, 6783 6001) and SAFRA Yishun (#02-V2 60 Yishun Ave 4, 6759-9737). 

Mermaid School

Indulge your siren fantasies and work your core and glutes at the same time at this mermaid school by self-dubbed "Singapore's first mermaid", Cara Nicole Neo. You get to put on a nice fancy tail, pretend to be a sexy work of fiction and swim with a flourish through classes which cover theory lessons on "mermaid lore" and core exercises. This is actually a serious course as you have to meet the minimum requirements of swimming one unassisted lap and tread water for 20 seconds before advancing from bronze for beginners to platinum for advanced learners.
