Tense lower back❓️Try this❗️
💢 Lay down on your back
💢 Keep your spine neutral (that means no gap between the small of the back and the floor)
💢 Bring the legs up in the air without losing that tight spine against the floor
💢 Straighten one leg and alternate with the other one
💢 Now push your heel up toward the ceiling to activate your hamstring
This is a great exercise to activate the parts of your body that are not working with your lower back muscles to stabilize your trunk better.
