A lot of great advice already from
@BGreen and others. Just a couple notes.
@BGreen Great advice! Does any of the workout advice (or maybe just how to go about it) change for a teenager who's still growing vs an adult?
Yes. Until PHV (roughly maturity) strength training should be limited to body weight exercises, i.e. no weights.
HS freshman is that like 14? I would disagree with Scottsskier slightly on the FIS skis and would get a junior race ski instead. 155 for SL. Although, on second thought, you do have the weight and height, so a short FIS ski would work, especially a well used one. Make sure to check the binding DIN range when you buy, make sure it starts no higher than 4. Use an online calculator to find your number and don't say you're a racer, as you're not yet. I would think you're around 5. If the ski keeps coming off for no reason as you go through the ruts, crank it up half a Din until it stays put. But make sure to take them to a legit shop to set them up initially. - it's not a DIY.
I ended up coaching a bit of HS as well for a few years and, if it's like up here, you should know that there is little gate time, little training time and sub-par
coaching, in general (present company excepted ). Check the schedule as in training days vs race days.
I don't think instructing and racing will work, unless the instructing helps keep you on snow. Instructing at your level is not focused on making the ski perform, which is what racing is all about. You'll get to babysit noobs and kids more than actually ski.
Hawx is not a race boot. Not even close... but may be good enough in the first year if it is fitted well. Likely it's too large though and will cause issues with technique. Do the shell fit test (Google it) closer to the beginning of the season, as you're still growing... if it's the right size (just below painful
) but then gets tight and painful as you're growing through the season, take it to a shop, they can fix that to get you through the season. Keep an eye on your feet - problems sometimes develop quietly.
Back to coaching... You will not have an easy time learning to ski well and in the long run, that's what matters. The racing part will just get in the way and slow down learning. It's fun though, right? The race training is good, but getting into courses before you ski well again will slow down your learning.... But that's that. I don't bring it up to discourage you - it's all good fun in the end, but to emphasize what to watch out for, if you're serious about improving your skiing.
Its slalom, specifically, so the best useful advice is probably this: DO NOT cross block as long as you can. It will completely mess you up. You'll have to trust me on that. Simply duck the other way (angulation is a very good thing) and worst case scenario, id you get close enough, clear the gate with the inside hand.
When should you worry about cross blocking? Let's say only when you can shin all the stubbies in a course (the little gates that are knee height), for starters.
Slalom is mean, up close and personal. Make sure you have your protective gear -
@ScotsSkier listed that.
Anyways, remember to have fun... that's why you're doing it.
Have fun.
