You knew that it is recommended to pick things up from the floor by using your legs.
What you probably did not know is that besides avoiding extra stress to your lower back; when you pick things up by bending your knees rather than just bending from your waist; you are practically performing a squats repetition each time.
As you may already know, squatting is one of the best exercises that work your lower body including your gluteus.
Now you know. Don’t just bent over, squat down as you pick things up and get buns and legs of steel.
