Hi i am new here and i was wondering if d ball makes you any faster. i am getting ready for my senior year of track and have a good chance at taking state. so i want to better my current time of 11.29. I have a pretty fast forty (4.37)but i have aways had a problem with muscle endurance( i die out at about 60 instead of gaining speed). i just want to know if dball will help me maintain my speed longer or slow me down cause the added weight? Also the reason i want to get bigger in the first place is because i am going to be playing college ball this coming fall. thanks
