  • A kettlebell workout (using a 26lb, 35lb or 40lb kettlebell): a fun, full-body conditioning workout that improves strength without building bulk. A 2010 study published by the American Council on Exercise ACE found that a kettlebell workout can burn up to  20 calories per minute. Don't own one already? See our pick of the best kettlebells!
  • A Tabata workout: Similar to HIIT (high intensity interval training), Tabata workouts are characterized by periods of intense activity followed by a brief period of rest. Another study published by ACE found that participants who did a 20-minute bodyweight circuit (including push-ups, burpees, squats, and lunges) burned an average of 15 calories per minute - almost twice the rate burned during a long run.

Currently Wellbeing Editor across several women's titles including Woman&Home, Woman and Woman's Own, Faye has worked in the magazine industry for over 15 years. She has previously interviewed celebrities for the Fit&Well brand. Having previously been the go-to sex columnist for Now magazine, there isn't much she won't discuss when it comes to women's health - which is important, as Faye's a firm believer that feeling good on the outside starts from within.  

Faye’s fitness routine is more focussed on finding inner balance rather than burning excess calories – think mindfulness, power breathing, yoga and plenty of walking in nearby woodlands rather than a sweaty HIIT class. Having been vegetarian for almost two decades, Faye’s also passionate about eating well. She currently swears by her daily mix of probiotics, vitamin D and B12 to help boost energy instead of sugary treats. 

Out of the office, Faye loves to binge-watch Netflix documentaries, plan cruise holidays and talk incessantly to anyone who will listen about how much cats rule. And you'd be surprised how long that can last!
