That Girl workouts are fun yet they push you and your muscles to the limit. You become aware of muscles groups and a range of motions, as if re-discovering your body all over again. The workouts challenge your body and make you think about the movements you are doing. You will sweat and you will laugh – THAT GIRL workouts are one of the best I have discovered in the last few years.

Forget what you know about the gym routine: over 20 years in the making, Christina’s technique does away with the humdrum of machines and circuits and uses her own smart, and always fun, training and self-taught, tried and tested movements to motivate the body, muscles and mind to change – with dramatic effect. And it doesn’t matter what your starting point is, because whether you’re a gym shy newcomer or a regular that isn’t seeing change, this method breathes new life into fitness so you can expect those sculpting and toning changes follow fast.

Christina transformed my body and my attitude towards exercise. I got the kind of curvy yet lean and toned feminine shape I always wanted. I shed 3 stone and gained a new love of working out!

I first met Christina when trial-ing her workout method for an InStyle feature. After seeing a massive difference in my legs within a mere week, I’ve been hooked on my weekly sessions. She has a real knack for knowing how to sculpt a woman’s body by ditching those uninspiring gym machines, and relying instead on her own unique combo of bodyweight exercises and small range of equipment. Plus, she makes it easy to maintain a newly sculpted physique thanks to thatgirl online workout videos. These mean you can perform in the comfort (and solitude) of your own home. She’s simply the trainer to have on speed dial!

Christina got me back in shape after my son was born. Thank goodness for her!
