7. Spinal Twist
Why You Should Avoid It: While twisting with a bar or broomstick across the back seems like a low-impact way to work the back and engage in some rotational movement, it puts pressure on the lower back.
What You Should Do Instead: A cable rotational row builds strength in your torso, arms, and back. The movement should look and feel like you’re trying to start a stubborn lawn mower. So you’ll not only build rotational strength with less stress on your back, you’ll have better success getting your old Toro to crank.
