It is a myth that you need to be able to do a perfect split to have a beautiful toe touch. If you actually look at one from the side, you will see that your body is in a "sitting" position and your legs come up to meet your hands. Also, you do not "touch" your toes - you should reach for your heels; this gives the illusion that your legs are "inverted or hyper-extended". Here are some tips to keep in mind:
Toe Touch Jump Execution Tips: Arms: Reach for your heels, not your toes
Legs: Bring your legs UP TO YOU, don’t reach down for your feet. For the "inverted / hyper-extended" effect, keep your back completely straight and roll your hips under you as you reach for your heels at the top of your jump.
Feet: Point Your Toes!
Body: Keep your head and chest up. Keep your body in the "sitting" position and do not lean forward to reach your toes.
Landing: Make sure to land properly with your feet together, toe to heel and with bent knees.
Toe Touch Exercise Tips:
One great exercise for the toe touch is to sit on the ground with your legs in a tuck jump position. Lean back, into your "sitting" position, and do your toe touch jump on the ground. Yes, you should feel this in your quadricepts (the muscle on the front of your thigh). Repeat 3 to 5 times.
