The high intensity body booster workout

Christina Howells is personal trainer to some of the hottest bodies in London including fashion and magazine editors, models and actresses. Charli Cohen is one of the UK’s brightest new sportswear designers. Together they run ThatGirlLondon.com, an online series of targeted nutrition and workout plans.

Here, Christina has created an efficient and highly effective interval training programme to use alongside your Project Bikini workout that you can incorporate 2-3 times per week in the smallest of spaces.

Christina says, “Interval training consists of intense periods of work with short recovery segments, allowing you to keep the workout intensity high while still maintaining form. The beauty of this form of training is it maintains lean muscle tissue while it also boosts your fat burning potential post-workout, so your metabolism stays boosted way after your session.

“This is a fun interval cardio session that I created for my clients who easily get bored or needed a challenge. It really is effective for working the legs, coordination, agility, mobility, flexibility and of course stamina. You can easily incorporate the intervals as part of a power walk or running sessions.”

The idea is make the intervals challenging so you want to put your all into it. Make sure you really do lift the knee up high and keep the movements dynamic.
