I recommend having at least two sets of dumbbells - a heavier and lighter set. Range 5-20lbs.

We use these from time to time - I recommend a variety pack, or a medium strength one.

This is my favorite yoga mat, but it is an investment. Not mandatory.

We use a bench from time to time - not mandatory, but nice to have

Roughly 36-48 inches long and around 1 inch thick in diameter

This is a great set and keeps the dumbbells organized in your space.
