The style of toss I am talking about are when the guy does not squat behind the girl and throw, but rather when he stays more upright and performs more of an upright row. In other words, it's a toss, not a throw.
As far as what the guys need help with:
- continuous speed during the toss
Make sure the guys are getting their arms moving first and
THEN following through with their legs. If a guy stands up too quickly when performing a toss, he will slow down in the second half of his toss since your arms are not as strong as your legs.
- avoiding "dead-lifting" the girl/not letting her jump
Make sure the guy follows the girl down in her dip, but do not push her down or pull her off the ground. As she starts to jump, accelerate your arms and follow through with your legs.
- straight up-and-down motion/not pulling
This will come along with the above two actions. Make sure when they accelerate their arms that they are doing a motion like an upright row and watch that they are not bending with their back instead of their legs. If they bend over the girl and pull using their back, they will pull the girl in causing her to get out of a proper body line and causing the guy to throw her over his head in many cases.
- finishing the toss (flick, etc.)
Be sure the base and top are releasing at the same time. Make sure the guy is fully extending his arms before flicking. Going back to the first few points, if his arms have slowed down and he is out of power, he will not be able to fully extend his arms and, consequently, will not flick at the top.
As far as what the gals need help with:
- stopping extra hip "thrust" motion at the top of the toss
I'm not exactly sure what you mean by this. If it's that her hips are getting out of line, there are a number of things that can be causing that. Watch that the flick is straight up and not forward (that will push her hips forward). Watch that she does not "pinch a penny" (doing that often does make the hips go forward...have them pull up instead). Be sure that the girl pulls up with her shoulders and does not settle them back or forward. Be sure the guy is not "toeing" her in the stunt as that will cause her hips to drift forward as well.
- speed on the jump from the bottom
Be sure she does not over-dip. If she is going too low in her dip, it will be difficult for her to explode up. Along similar lines, have the girls work on explosive power drills and exercises (does your team do plyrometric type activities/have access to a weightroom and a trainer to put together an activity-specific exercise program?).
- body alignment as a whole
See above comments about hips.
Hope this was helpful and I'm sure others will have some useful information.
