What are the effective shin splints stretches?


Here are some of the effective shin splints stretches:
1) In a kneeling position, point your toes out behind and gently sit back on your heels pressing the tops of the feet towards the ground.
2) Standing arm length from a wall, put your hands on the wall while keeping your feet and knees straight, then lean forward as far as possible.
3) Standing with your feet flat, bend your knees forward as far as possible keeping your heels on the floor.
4) Put feet flat on the ground and have a partner hold them down. Partner applies resistance to your toes and you lift them up against the pressure.
5) Sitting with your left ankle on right knee, apply pressure to inside of your foot (near big toe) with hand, then and turn your foot up and in, using the leg muscles.
6) In the same position as above, put pressure to the outside of the foot (near little toe) with your hand, and turn foot down and out using the leg muscles.
7) In the same position as above, put pressure to the top of foot (near toes) with your hand, and lift the foot using leg muscles. Repeat these with the right ankle on the left knee.
8) Sit on a table or chair attach a weight (a bucket filled with stones or sand works well) around the foot. Without bending your knee move your foot up and down from the ankle - Start light and work up.
9) Attach one end of a stretching exercise elastic band to the leg of a table or sofa and loop it around the end of the foot. Move your foot up and down and side to side against the bands resistance. Try to draw the letters of the alphabet in the air with your big toe.
10) Stand erect and raise up and down onto your toes several times. You can make it harder by doing it while standing on a step and allowing your calves to stretch over the edge of the step.
11) While sitting lower and raise your feet with the heels on the ground as high and quickly as possible for 60 seconds. This is a great one to do during work days while sitting at your desk.

What is a battle axe?


A battle axe is an arm-length weapon borne in one or both hands. Compared to a sword swing, it delivers more cleaving power against a smaller target area, making it more effective against armor, due to concentrating more of its weight in the axe-head.

How to build height without medicines suggest only exercise


1. VERTICAL HANGING:
This is a simple but an extremely effective stretching exercise which you can do at your home. All you need to have is a solid bar strong enough to hold an individual, fixed at least 7 feet above the ground such that the distance between your feet and the floor is atleast 4-6 inches. Hold your arms neither closer nor wider and start hanging. Hold as long as you can, and as you begin to tire, slowly swing back and forth and try to touch the ground with your feet. This will flex your spine and elongate it, so that you can add few inches to your height
Make sure that you flex your spine while stretching, and not merely twisting your wrists
Perform the Workout 3 times a week for optimal results
2. COBRA STRETCH:
This is basically a Yoga exercise intended to stretch your spine and make it supple and flexible, so that the cartilage between your vertebrae grows thereby increasing your vertical height
Lie on the floor face down with palms on the floor under your shoulders. Begin to arch your spine up leading with your chin. Arch as far back as possible. Do 3-4 repetitions with each repetition lasting between 5-30 seconds
3. PILATES ROLL OVER:
This is an excellent workout to stretch your spine and lengthen your upper body. Apart from your spine, it also stretches and lenghthens the vertebrae of your neck.
Lie on your back with your arms along your sides, palms down. With your legs together, extend them straight up toward the ceiling and bend them backwards so that they touch the floor. It may not be possible to touch the floor at first, but you can do this by practice. The more your stretch, the more your spine lenghthens
4. FORWARD SPINE STRETCH:
Sit up tall on a mat. Your legs are extended about shoulder width apart, and your feet are flexed. Reach the top of your head but let your shoulders stay relaxed. Inhale and extend your arms out in front of you and slowly bend forward and try to touch the tips of your toes. If you are able to touch your toetips, stretch even forward so that your spine is flexed to the maximum extent.
Do 3-4 repetitions and hold each stretch for 10-15 seconds
5. ANKLE WEIGHTS: This exercise is solely intended to increase the length of your lower body, by stretching the cartilate between your knees. Prolonged stretching will elongate the cartilage and increase its mass, which in turn will increase the length your lower body
Sit on a high chair and use a Ankle weight fastener to add weights to your ankle. Start with small weights initially and gradually increase as you go on. Allow your legs to stretch down with the pressure of the weights. Once completed, remove the weights and relax your legs by kicking your legs gently for 5-10 times, and then vigorously for 5-10 times. This will flex your knee cartilate to enable it to grow in length

I've got an Elna 634 overlocker, and want to turn


Just trim the fabric to the desired hem length plus one inch, then overlock around this raw edge with thread close colour match to the fabric.

You then have the choice of either stitching around with a stretch stitch on your sewing machine, or hand sewing.

Being lycra shouldn't change how you hem them unless the trouser leg is extremely close fitting and the hem seam is going to be under tension.

My first choice would be using a twin needle in straight stitch from top side but this finish can pop/break if the hem is under tension. But perfect for most knit hems.

If you hand sew then you can turn up hem allowance and put a length of fusible hemming web inside the hem allowance and press it to hold. Then do a back stitch hand sew around to hold hem in place.

If you sew with the regular sewing machine, then use either the stretch stitch or a very small zig zag, and a ball point or stretch needle.

On ready to wear you would see a coverstitch hem but your overlocker doens't have this stitch.

Hello, so for some reason the needle is sliding down the vinyl towards the center every time we go to play it. it just slides across! makes no sense, the needle is not broken and we have been trying to...


needles never seem to look broken But a tiny chip on them will make the player do exactly what your describing, as far as the counter weights,, spin the player by hand , click the handle to make the arm begin to position itself at the beginning of the record, Now, before it drops, slow down the hand spinning, and set the weight so that when the arm is supposed to drop it doesn't,, in other words balance it to be level, No up or down motion, without a weight scale to do this by the book, try this , Its always worked for me, tape 2 pennies to the weight at the rear of the arm, and one penny to the head of the arm, again, adjust it to be level,, then remove all the pennies,, the arm will have about the correct weight they require for the needle to be correct,, if it still slides, you have a bad needle
