One option for gear free mobilizations are the 7 that are emailed when you join TRS.
They are also located on the TRS App in the bonus content.
The app is free use your log in for the site to log into the app.

If you search the archive you may find more gear free mobilizations.
A baseball or softball could be used in place of a lacrosse ball.
A kids playground ball can be used for ab/core doses.

A second solid option is the Functional Yoga For Athletics Course
This is an excellent course the majority if not all requires no equipment.
