Insaniacs Review

London Insaniacs

I can’t make excuses any longer – the simple fact is, since my half marathon over 4 weeks ago I have abandoned any attempt at a fitness routine. If truth be told I’ve mainly been spending my nights curled up in bed watching multiple episodes of The Good Wife with a steaming mug of hot chocolate. It is autumn, after all! And after the amazing summer we had the change in weather really makes me want to hibernate.

Regardless though, I’ve been feeling the urge to start training again. I’d heard a lot about the London Insaniacs classes and after getting hits of fitspiration from their Instagram updates felt like it was time to give it a go.

Insanity is based on High Intensity Interval Training (HIIT), but instead of short bursts of exercise interspersed with periods of rest, Insaniacs exercise for longer periods at maximum intensity, followed by very short rest intervals. The intense exercise forces you to use fast-twitch muscle fibres not normally used in cardio workouts, which then continue to burn fuel even during lower intensity exercise.

I definitely felt the burn during this class – and you’ve probably guessed by now that it was, for want of a better word, INSANE. High jumps, lunges, crunches, press ups – you name it, we did it. Starting off at a high intensity you would do the first round of 3-4 exercises, followed by a short rest, which then led into the same routine but faster, and on it went until you were at the point of physical combustion.

The lovely but unyielding instructor Tanya led us through 10 minute sections which focused on specific areas e.g. Core, Strength and Agility. Each section used certain muscles, working different areas of the body. This definitely highlighted my weakest areas, though I’m already well aware of my pathetic inability to complete a full press up! There were moments when I wanted to collapse on the floor and plead for sweet mercy, but after finishing the class I had the biggest sense of achievement for making it the whole way through without too many inadvertent breaks while Tanya’s back was turned.

At £5 for first-timers it’s one of the cheapest classes in West London, so if you’re looking for a workout to help build endurance, get you toned and burn calories then I’d definitely recommend giving Insanity a go.

  1. […] The British Wheel class was a very gentle introduction to some of the basic asanas and focused a lot on moving slowly in time with the breath to get the most out of your practice. Whilst this was a great class, the space around us was so noisy that it became difficult to relax as fully as we were meant to. I find that faster, more dynamic yoga helps to block out external distractions (as well as helping to ease my sore muscles post -Insaniacs!) […]

  2. […] barely lift my feet off the ground doing squat jumps, which was a throwback to when I tried the Insanity workout. Just remembering it now makes my legs start […]
