I find that Katya Kinski’s videos are brilliant for core strength and overall fitness, and complement running, helping me to avoid injury. Katya mixes very clear instructions with a good dose of Russian humour, making the videos easy to follow and enjoyable. You can pause/rewind the videos to make sure you are doing the exercise correctly. I can fit the workouts in at a time that is most convenient, and as regularly as I fancy. I can highly recommend Katya Kinski Online videos!
