: HOLY COW this is so hard! BALL 🏀 #PLANKs & #SQUATS. I'm using a medicine ball to balance my plank, once you can hold the plank...walk feet out 4 counts and do a #chestpress #pushup. walk them back in and do a #tricep #pushup. NEXT jump into a #SQUAT position and roll the ball back and forth in that squat position! ⚠️. If you have knees or lower back issues DO NOT do this exercise! Listening to your body will is key... If it hurts don't do it! #bunsofsteel #getfit #plankexercises #workoutsthatwork #besteverexercise #fitnesspro #tamileewebb #jumpsquats
