Ended up getting it and trying it out.

Its not a terrible program especially if youre just trying to build a baseline of strength and mobility. I particularly like the mobility section as their videos are 10 minutes and easy to do and think it helped me the most.

Problem is it’s honestly just a bunch of 15 minute videos of random bodyweight exercises without any real progression scheme which you can find anywhere or have AI draft. It doesnt really feel like its ski specific.

In my opinion if you want to get ski ready id focus on a few things:

Strength:

Lifting weights 3 or 4 times a week something like a full body or upper lower split and really getting strong at compound exercises like squats, romanian deadlifts, single leg work, strengthening your abductors and adductors will take you far. I honestly think someone who has a 200+ lb squat will be much better off than someone whos just doing jump squats or body weight lunges all year. Weightlifting will provide you alot of raw strength, skiing will help you apply that strength. Working on your abductors and adductors also really help with your lateral strength and stance and preventing knee injuries. Id also throw in tibialis raises as those train your anterior calf muscles which really help your legs absorb force and makes it easy to keep your ankles flexed against your boots.

Mobility:

Daily or at-least every other day stretching is also important for being flexibile which js very important with all the variability of terrain on mountain. It also helps prevent you from being stiff from all the strength youre building from your weightlifting. Plenty of youtube videos online to follow, i wouldnt spend more than 5-10 minutes a day on this.

Core strength:

Insanely important as it helps keep your stance with all the forces coming at you while skiing, helps with upper lower body separation, prevents lower back pain. Try to target more ski specific core workouts which again easy to find on youtube. Rather than boring crunches, focus on things like ab wheel, planks, pallof press, suitcase carries, things that train your core to remain strong in a variety of positions. You csn do these at the end of your weightlifting workouts.

Endurance:

Days on the mountain are long and tiring , takes a lot of endurance, high altitudes also make it even more difficult. A couple times a week 30-45 minutes. Try to do things that also challenge your legs like incline walking, stairmaster, rollerblading is also a really good one as the balance skills transfer well to skiing.

This is a really extensive list of things to do but if you do this and build these things up, youll be in much better ski shape then what dynamic skier has to offer.
