Lacrosse Balls Since I don't have room in my bag for my beloved Theragun, I am bringing these small Kieba Massage Lacrosse Balls ($10) which can get into my sore muscles and trigger points for before and after the race. They barely take up any room in my bag and work wonders. Image Source: amazon.com Kieba Massage Lacrosse Balls $10 from amazon.com Buy Now
