No Prowler for Superhero Program?

Salut CT

I am thinking about doing your 6 weeks to Superhero Program. The thing is that my house is tiny and there is no park or open public space nearby. I can manage todo medicine ball throws, but aside not having any type of sled (I could have someone doing one for me), I have no place to to that.

Is there still a way of change that exercise for another without turning your program into a Frankesteined Superhero version?
