I have a Dilemma

Say I want to do Foundation one 3 times a week and each workout I want to do all of the Foundation exercises (I think it's called F7). Some of them require weights and because currently I can only work out at a park it would be of a great inconvenience to carry the weight in my backpack. Any solutions? Is anybody else in a similar situation?

Well, you can either split the work or re-order things so you have a batch of exercises requiring equipment which you perform in one location, followed by a quick trip to the park for the rest.

Otherwise its pretty much take the required equipment to your training location

Hmmm...decisions, decisions. I'm thinking due to the fact that for the RC progressions I will need both access to a pull up bar and weights I might have to go to the park. It will be interesting carrying weights up a very steep hill. 

I've done a home/park split before, and it can work. It can get a bit time consuming though

Yes indeed, that's part of my concern but I guess you have to work with what you got. 

I always carry all my equipment to the park in a small rucksack, rings and straps, measuring tape to control height, a dumbbell bar (2 kg), plates (5kg total weight), 2 yoga bricks, bunjee straps, ankle weights (2 kilos), chalk and a broomstick for shoulder dislocates. With that I can perform all of the strength and mobility drills and the stretches series without problems nearly everywhere I go. It's quite convenient for me.
