    Mini-Stability Ball Exercise Manual

    Mini-Stability Ball Exercise Manual Sculpt lean muscle, increase mobility, improve your posture, and strengthen your core with this easy to use exercise guide Table of Contents Page 1 Introduction Page 2-21 Abs Page 22-27 Thighs Page 28-37 Glutes Page 38-41 Arms Page 42-43 Back Introduction The Open BarreTM Mini Exercise Ball is used to more effectively & efficiently target the muscles you’re strengthening. It’s very important to pay attention to the correct alignment of each exercise, so make sure you read through and understand the set-up of the exercise beforehand. It’ll ensure that you’re keeping your body safe as well as using your time wisely. The ball is inflatable and deflatable, so you can use the straw (or a pump) to fill it to your desired firmness level. Generally, the firmer the ball, the more challenging! It will start to lose air over time, so you can simply pull the white cap out (or dig into the ball to locate the tip of the plug and press it out from the inside), blow/ pump more air into the ball, and replace the cap nice and tight. It’s ok that some air will escape before plugging it back up with the cap. Just make sure that you blow up the ball a tad more than desired... and of course try to be quick with the plug to stop the air-loss. For more exercises and tutorials, visit http://vimeo.com/openbarrefitness. 1 Abs / 1. Incline leg-drop Starting position set up: - Lying on your back, press your hips up and position the ball directly under your hips/tailbone.

What are Team R's options? 2) Dixie High School only has 13 players. In the first half, 2 players get hurt and cannot return. Late in the 3rd quarter, Dixie scores a TD to put them down 77-6 and two more players are hurt and cannot return.

That’s not the case. It could have been me. It could have been anybody on this team. None of us are doing a good enough job to make plays and help us win. As disappointed as you are for Kyle, you’re kind of excited for [QB Tim] Tebow because he’s getting a chance. We’re just hoping that translates into wins. “At the end of the day we’re 1-4 and that’s the reason why we’re not cheering. We’re 1-4 and we haven’t been playing good football. So there is no reason for this locker room to be excited at the end of the day. We have a long way to go to get ourselves close to being competitive and we’re not there. That’s the reason the locker room is kind of subdued. And again, the headline is probably Kyle and it could’ve been any of us, but the fact of the matter is that it’s Tim Tebow and he has such an aura about him and a following that’s such a big story.” On quarterback being the most important position on the team “It is but the guys around him can help him play better whether it’s the guys on his side of the ball or the guys on the defensive side of the ball.

  • Die Spielerpositionen Beim American Football

    Die Spielerpositionen Beim American Football

    Die Spielerpositionen beim American Football Jeweils elf Spieler gehören zu einer Offense und Defense im American Football. Da kann man leicht einmal den Überblick verlieren, welche Aufgaben die einzelnen Positionen überhaupt erfüllen müssen. OFFENSE Quarterback (QB): Der Spielmacher des Angriffs, der bei jedem Spielzug den Ball entweder zu seinen Wide Receivern (WR) werfen oder zu seinem Running Back (RB) übergeben kann. Der Quarterback kann wie der Running Back auch selbst laufen. Wide Receiver (WR): In der Regel die schnellsten Spielern auf dem Feld. Sie müssen die Pässe des Quarterbacks fangen, um im Anschluss daran möglichst weit in Richtung Endzone zu sprinten. Running Back (RB): Der Ballträger, der sich nach der Ball-Übergabe durch den Quarterback den Weg durch die Verteidigung bahnt, um in die Endzone zu kommen. Running Backs können (ähnlich wie Wide Receiver) auch Bälle fangen und so in die Endzone laufen. Fullback (FB): Einer der Ballträger, der selten dem Ball bekommt, sondern dem Running Back den Weg durch die Verteidigung freiräumt. Tight End (TE): Eine sogenannte Hybrid-Position mit unterschiedlichsten Aufgaben. Kann sowohl Bälle wie ein Wide Receiver fangen, als auch große Verteidiger an der Line of Scrimmage (LOS) blocken. Offensive Line (OL; Guard und Tackle): Spieler der Angriffslinie, die entweder den Verteidiger aufhalten müssen, um dem Quarterback Zeit zu verschaffen oder dem Ballträger beim Laufspiel Lücken freiblocken. Center (C): Der mittlere Spieler in der Angriffslinie, der bei jedem Spielzug den Ball zwischen seinen Beinen hindurch zum Quarterback ins Spiel bringt (Snap). Er hat ansonsten die gleichen Aufgaben wie der Rest der OL. DEFENSE Defensive Tackle (DT; gehört zur Defensive Line): Die inneren Spieler der Verteidigungslinie, die sowohl den Quarterback im Passspiel unter Druck setzen oder zu Fall bringen, als auch den gegnerischen Ballträger beim Laufspiel stoppen.
