Strength / Weight Training

I posted this in the try thread a few days ago but no luck so figured I'd try in here. I used to do quite a bit of gym work but that was probably 10 years ago now and I don't really have the opportunity to get to a gym on a regular basis so I'm hoping for ideas based around body weights and resistance bands that I can do anywhere.

Does anyone have any recommendations for a strength and conditioning program I can play with this winter.

I might end up doing a few tris again next year so I’m after stuff to build a foundation for s/b/r. Ideally I’d do about 60mins a couple of times a week and am after something focussed around body weights and a maybe resistance bands. I’ll be traveling quite a bit so weights isn’t really an option.
