Squash training advice, please

[Yasai]

Hi, lovely people. I constructed a squash arch,
like this https://www.pinterest.co.uk/pin/415316396863779274/ and have two squash growing up one side and one on the other. Now that they have reached the other side, can I train them to go back up and over to the side where they initially started growing... or is this a bad idea? The leaves are massive so I know the arch will get very crowded but it's either that or just let the rest of the plant trail on the ground.

Any advice will, as always, be greatly appreciated. Cheers.

Yeah I'd think that should be ok. Depends how flexible the plant is really? You could train it along the ground around the bottom of the frame, then send if back over the frame from where it started from.
Hopefully that make sense

It does make sense, thank you
