I am still growing and not as mature as a typical sophmore, but still what would this come from? I have been lifting, but I want to find something that will prevent injury, but I also want to find something to do to improve my power output and speed. I have really good endurance, but no speed and its definatly my biggest hold back. Will general strength help with both or is lifting the thing to do. I have heard that it can stunt your growth and I don't want that.","date_added":"Jun 9th 2012, 7:24pm","nest":0,"liked":false,"member":[],"can_delete":false,"item_id":8466,"item_type":"video","pb_image":"i\/no_avatar.png","pb_title":"JJM","pb_url":"profile.php?member_id=5897","pb_url_dns":"https:\/\/JJM.runnerspace.com\/","pb_wally_id":"1967"},"512060":{"pb_id":"5897","pb_type":"members","likes":"0","parent_id":"0","pid":"512060","comment_id":"512060","member_id":"5897","comment":"This thing looks so simple, but tough at the same time pretty darn hard. Yall are are right though, I am definatly looking forward to trying it out. But, I also can't do the high ball toss. So will this improve one's lactate threshold at all? Cause I am injured right now and can't run or bike, and I absolutly hate swimming.","date_added":"Jun 9th 2012, 7:24pm","nest":0,"liked":false,"member":[],"can_delete":false,"item_id":8466,"item_type":"video","pb_image":"i\/no_avatar.png","pb_title":"JJM","pb_url":"profile.php?member_id=5897","pb_url_dns":"https:\/\/JJM.runnerspace.com\/","pb_wally_id":"1967"},"512059":{"pb_id":"5946","pb_type":"members","likes":"0","parent_id":"0","pid":"512059","comment_id":"512059","member_id":"5946","comment":"It looks fun, I do a lot of those exercises but never together so i will have to test it out.
