For the next half hour, you’ll be carving your core from every angle and achieving the defined muscles that come from the more intense squats and lunges required when working out on a stability ball. “Most of these moves provide a ton of glute activation and a focus on hamstrings – the combo you need for a firm butt,” says Traci Copeland, a Nike master trainer in New York City who has perfected a way to get the most shaping power out of this go-to tool.

“Adding a stability ball ups the core engagement throughout your workout,” Traci says. “Whether the exercises are standing or horizontal, you’ll need to keep your abs tight to control the roll of the ball.” Take the traditional crunch. You get 20 per cent more firming of your obliques if you curl on a ball rather than on the floor, according to a study from the American Council on Exercise. It’s all about the balance challenge: If you do a Split Lunge using a bench (in which you lower into a single-leg squat while resting the top of your other foot on the bench behind you), for example, your foot isn’t going anywhere because the bench stays put. But with your back leg raised atop a ball, you have to work harder – and engage your core – to keep the ball from wriggling around.

As you can see by the images here, these moves have a beautiful flow that you just don’t get from your average sets and reps. Traci tapped her gymnastic, yoga and dance background (she’s danced onstage with Jay-Z, Beyonce and the Black Eyed Peas), and structured the workout so that there’s a rhythm to it. The Tilt, she explains, is a dance-inspired move that incorporates the feeling of training as a ballerina. Other exercises, like the Crab Toe Touch, are inspired by capoeira, the hot Brazilian martial art that integrates elements of dance and acrobatics.

Also, as with yoga and dance – in which you’re always striving to perfect certain sequences or tough poses – this workout gives you something to aspire to and provides that confidence boost when you ace it. “Whether that means getting through all the core exercises you struggled with last week or finessing one of the more difficult moves like the Pike, there are plenty of ways to keep tabs on your progress in this routine,” Traci says.

Plus, there’s a sense of being mentally present as you move that takes you out of the autopilot mode you might be in at the gym. “A lot of times, people aren’t really ‘there’ in a workout; they’re thinking about laundry or dinner or what they’re going to do later that night,” Traci says. “When you have that stability ball beneath you, all you’re thinking about is: How can I do this move without having the ball pop out from under me?” Keeping it in place requires you to go into the same zone you inhabit when holding a warrior III pose in yoga: Your mind and body must work together.

You’ll get a taste of how potent this muscle-sculpting approach is after just one session. Without becoming breathless, you’re building strength and attacking every single muscle fibre to cinch your abs, butt, thighs – everything, Traci says. “You might not be dripping sweat, but if you make it through the entire workout, you will feel it tomorrow,” she promises.

“This routine should make you feel energised and graceful – and excited that you left your comfort zone to try something different,” says trainer Traci Copeland.

YOUR WORKOUT

Warm up for five minutes with some dynamic stretches – knee hugs, ankle grabs, inner-thigh stretches, walk-out planks, walking lunges, arm rotations, trunk twists. Then do the following moves in order for 30 seconds to one minute each as indicated, with little to no rest between sets. Complete the circuit three times. Mix this workout into your routine twice a week for max results.
