Q: The reason you are in high school is to learn, so that has to be your primary focus. If you are balancing a full class load as well as a full practice and game schedule, that can be incredibly tricky. Make sure that both you and your coaches know that your schoolwork comes first.  If you know you’re going to be missing class because of an away game, talk to your teachers ahead of time to find out what assignments you’ll be missing. Plan to turn in your assignments early if you’re going to be missing class, or if that’s not possible, ask your teacher for an extension. Student athletes often miss class for games, and this makes it easier for you to fall behind. If you feel that you’re not fully understanding your class work, hire a tutor to help you keep up with the rest of your classmates.  If you can’t afford a tutor, ask your teacher if you can come in for extra help after school. The more you fall behind, the harder it will be to catch up later. You’ll save yourself a lot of time and stress by staying on top of the work. If you have a study hall in school, don’t use that time to goof off with friends. Instead, use it to cross a homework assignment off your list. If your teacher gives you time to work on homework in class, take advantage of that time as well.  If you’re traveling on the bus to an away game, use the time on the bus to work on assignments or do your class reading. Learn how to multi-task: do your reading while eating breakfast or study for a test while blow drying your hair.
A: Prioritize academics. Hire a tutor. Take advantage of free time.

Q: Lay on your back on an exercise mat. Place your feet on the fitness ball and bend your knees, pulling the ball toward your rear end and stabilizing your body. Hold your body steady and straighten your core by pushing your hips up. When you feel stable, extend your legs and roll the ball away from your body. Then bend your legs again to retract the ball.  If necessary, balance yourself by laying your arms at your side on the mat. Rest your back on the ground between repetitions if necessary. Aim for 4 or more repetitions per set and perform at least 2 sets. Get on your hands and knees on an exercise mat. Place the fitness ball at your feet behind you. Bring your feet up and balance them on the ball in a crouching position, supporting yourself with your hands. Then, extend your legs by rolling the ball back under your feet. Hold your core stable and face the ground as you straighten your legs. Hold the pose for 3 seconds before curling your legs in and rolling the ball toward you again. Perform 4 to 6 repetitions per set and at least 2 sets to work out your quads. Get into quad press position: hands on the ground (as if you’re doing a push up) and both feet extended on the fitness ball behind you. Tilt your body to the right, and lift your left leg off of the fitness ball. Then, use your right leg to roll the ball towards you. Hold for 3 seconds and roll the ball back out by extending your leg.  This can help you build muscle in your weaker leg. Or, switch legs while you’re doing single-leg quad presses. Try 5 reps with 1 leg followed by 5 reps on the second leg. This exercise will also engage and strengthen all your core muscles.
A: Do hamstring curls to engage your quads and glutes. Do a quad press to strengthen your quads and glutes. Try doing quad presses with a single leg to double the resistance.

Q: It is a ready-to-use alkaline solution of tough silicate material which combines with softer lime-free particles in conventional concrete mixes to form a harder surface which resists wear and dusting. It can be used on old concrete in basically good condition or on new concrete laid at least 14 days before. Provided the concrete is clean and free from surface water, the dust-proofer is simply poured onto the floor and spread out with a soft broom, then left to dry for 40 minutes. The floor is then washed with clean water. On very porous floors a second or third coat should be applied with 40-60 minutes between coats.  Ponding should be removed after 10 minutes. 40-60 minutes after the final coat the floor should be washed with clean water. When coloured pigments have been used on concrete or granolithic flooring, it is advisable to test treat a small area first to check that Dustproofer has no adverse effects on the colour.
A:
Add a concrete dustproofer and surface hardener. Pour the dust-proofer in the concrete. Add more if needed.
