Foam Roller

When used for balance or stability work, you can do the same exercises without the roller underneath you.  The roller is nice because it gives immediate feedback about whether we’re maintaining balance, but isn’t necessary.

When used for rolling out the muscles, you might find that you can use balls of various sizes instead.

Loop Bands

If you have longer resistance bands/therabands, you can tie them in a knot to create a loop.  Or, you could make a loop out of a yoga strap or belt and contract into it, which works great even though it doesn’t stretch.

Side-lying exercises will be effective without a loop band, just using bodyweight as resistance.

Pinky Ball

Tennis/racquet ball

Squishy Ball

Throw pillow folded in half

Therabands

For some theraband exercises, you might use a yoga strap or a towel. Even though it doesn’t stretch, as you pull on it *as if* it will stretch, you’ll work the same muscles even without moving.

Weights

A pair of canned goods, bottles of water, anything you have two of and can grip comfortably.

Yoga Block

When used to squeeze into, you can use a squishy ball or cushion instead.  When used to create a level change, you can use a thick book.

Yoga Strap

A belt or towel
