martial arts MMA: how to train older people to do double leg takedown?

[ST]

I want to be good at the double leg takedown, but im getting up there (way over 30, i'll leave it at that),,,my legs and knees are not very flexible or even that strong, but i did do karate when i was younger and now do a basic version of bjj (ground only).

any exercise/stretching tips to get the proper strenth and flexibility do really be able drop shoot down for a double leg? thanks...

Don't push yourself if you think you can't handle it. Just go for single leg takedown or sweeps.
