It sounds so logical that it must cost more energy to lift your feet and knees higher when running compared to not lifting your feet so high. For example, it costs more energy to lift an arm than to....eeee....not lift an arm. But that's not how it works, which I show in this video as I use my 3D cameras to measure how much energy it costs to move my body parts and how having higher feet and knees can be more energy efficient than having your feet close to the ground when you run.

"The best money I have ever spent. Great mix of humour, practical technique and theory. It’s brilliant and I have been telling all my friends about it. I’ve knocked 30 secs off my average pace to 4:30 and at 53 I’m absolutely astonished how relaxed I feel running. It’s also really helped my cycling my adapting similar techniques and visualisation. Thanks so much.
