I've done the programme before and then stopped due to work. Started again recently and just completed week 4. After the last two runs, whilst doing the warm down walk my right knee has given way, almost as though it's gone backwards?! It's not painful as such after but it's not a nice feeling when it happens. I've iced it and done my stretches and then it's not re occurred. Ideas??? What's going on
Ps I have good trainers, custom insoles etc so don't think it's gait related.
