One of the most common running injuries men get is Achilles tendonopathy, more commonly known as Achilles tendonitis.
The best releases to manage, prevent and treat Achilles tendonopathy is to start by releasing the plantar fascia on the sole of the foot with a tennis ball or prickle ball. Stand with one foot on a ball just off the base of the heel. Slowly roll the ball up the middle of the foot to the toes taking time to pause on any sore spots for 8-10 seconds. When you reach the toes you have completed one sweep. Go back to the heel and perform another two sweeps, one rolling the ball up the inner part of the sole of the foot then one up the outer part of the sole of the foot.
