UK Amateur Tennis Doubles

Almost none of the players in any of these vidoes will have received any tennis coaching. Most will be 40+ and play once or twice per week for fun, a few competing in the lower leagues of  Shropshire club tennis (UK). 
The courts are carpet/artificial grass, which I haven't seen featured in any North American amateur videos. Much better for our old knees!
I started playing in 2018, had a couple of lessons, loved it & haven't looked back!
Nora Batty?- the knee supports! 
Videos are filmed using the Swing Vision app. I'm an old fart and still getting use to it.
