@weshape: A strong core helps protect our spine and allows us to bend, rotate, carry, sit down and stand back up.

For older adults, Coach Tyler recommends 4 exercises in particular: Elevator, Reverse Crunch, Side Bend & Frog Deadlift. Get even more exercises for you for free by clicking the link in our bio!
