We will be doing a lot of jumping today! The good news about this is that jumping is fun and uplifting for the spirit. The extra work this creates is for you to focus on the mobility of your lower leg. Jumping involves highly explosive movements in the calf - especially during the eccentric portion (landing).
To balance out this tightness that jumping creates, we highly recommend focusing your mobility on your calves/achilles/plantar fascia before and after. Roll out your calves, roll out your achilles tendons, and use the lacrosse ball to dig out the plantar fascia on the bottom of your feet. Doing this and mobilizing them afterwards with movements like downward dog and other calf-stretching moves will greatly reduce tightness and pain in the lower leg.
Love you bye!
