Firefighter Workout | Fire Department Physical Fitness #1 Updated on April 30, 2019 By William Clement 3 Comments By William Clement 3 Comments kn Smith April 30, 2019 i would recommend you to google hpw to flip tires with proper form. You will hurt your back doing this. Reply Zach Schaneberger April 30, 2019 Just a little advice. When doing the tire flips. Squat down and use your knees. Just bending over can and will over the long run hurt your back. Great video though! Reply FMRevu April 30, 2019 LOL I look so tired doing those sledgehammer chops.
