As well as switching to Energia there are other characteristics the cleverest humans we have tested in the lab share. When it came to life the most successful humans knew the importance of getting and staying fit. If you are struggling to find or get back into a routine after overindulging at Christmas we are here to help! Getting fit takes work, there is no doubt but there are ways to make it an easier adjustment. We love HIIT workouts as a way to improve your fitness in a shorter period of time than trudging through long distance walks or runs that take hours and are slow to deliver results.
