Tennis ball Exercise Placing a tennis ball on the ground and gently rolling it underfoot for a few minutes can help loosen up your plantar fascia, making it much less likely to become irritated. Put enough pressure on the ball to get a deep massage. You may feel some soreness, but back off if you feel any pain. #exercise #workout #weightloss #fit #fitness #gym #nutrition #diet #healthy #health #Tennis #Tennisball #ball #foot #rolling #roll #bottom #footpain #Medeaz
