californiagrown - thank you for all that! I am learning. :)
The trail I'm climbing is just like you're describing. No heart issues hopefully - don't put me on the cart, I'm not dead yet! Do you know what a healthy 60 yr old is like? Are you in your 20s? :tdo13:
I ran sprints this morning, had to hurry up before meetings. Will ride the bike here shortly.
Never forget "the worlds greatest stretch". Seriously though, google it, and do it on the last few walking lunges.Quote:

Heart health is nothing to mess around with or push so i would just make sure your Doc has done some recent heart checks and gives you the greenlight to push it.Quote:

ok
Hahah great minds. Soon as I posted that I remembered the movement but couldn't think of what it was called!Quote:

The eccentric load is catching your body on the way down while you're falling from whatever height you jumped to.Quote:

The area under the curve will be almost identical assuming you return to your start position.
In terms of generating muscular strength and also tendon and ligament stiffness doing sets quickly and unbroken is probably slightly suboptimal, but in terms of generating muscular endurance/work capacity/fatigue resistance (whatever term you want to give to the ability to do sustained, repeated, high intensity but submaximal muscular work) doing the sets quickly, unbroken, and with short rests is probably optimal. Choose your own adventure in how you program it based on that.
Like I said above, I think there's more nuance to how and what someone's goal might be than this implies.Quote:
Its kinda like burpees. You can do burpees for time or amount and do them as efficiently as possible to maximize the competition benefit (which is what crossfit typically does), or you can do them "correctly" to maximize the training benefit. We arent doing leg blasters in a competition, we are doing them so the training benefit carries-over to skiing 2 months down the road.
I'm not sure how you can argue that catching yourself from a higher jump doesn't result in greater eccentric loading...assuming you're hitting full ROM regardless. Like, you'd be arguing against F=MA.
And landing "softly" is important so you achieve the kind of knee/hip flexion common in skiing... I. E. Full ROM on the lunge/squat jumps... unless you ski stiff legged never bending more than 20 degrees?
Careful, you're arguing with an actual physiologist :D
I've had to read these posts more than once, but I think I see the value and I think I'm headed in the right direction.
So here's something else to chew on that I haven't mentioned before. I take my dog out every day for a walk/run/hike at first light. For the past month I've been wearing ankle weights. Staying out of zone 2 mostly, just a slow grind. My army son says there can be some injury problem with ankle weights and I say they help me feel light footed on the ski hill.
Thoughts?
I like ankle weights for things like leg lifts while laying flat on the floor. For walking I don't think there is much benefit to weighing your ankles down maybe some extra weight in a well fitting pack or a waits belt? Put the weight where it should be which is a more natural thing for your body. Just my 2 cents.Quote:

Dropping from a higher height on squat/lunge jumps (because you jumped higher) means you are having to decelerate from a higher speed over the same full ROM. F=MA. it really is that simple.Quote:

Can't say I've seen too many real nutritionists argue that. Regardless, physiology is a much "harder" science than nutrition.
I mean, you're not wrong, but for regular people we're probably talking only a few inches difference in jump height so the velocity difference may not be enough to affect actual outcomes. I don't have a dog in this fight, but I'll agree with ptavv that the crux is the goal of the workout, i.e. peak power vs. muscular endurance.
I didn't do a good job drawing out the conclusion of what I said.
It's true there's more eccentric load if you jump higher, that's not really disputable.
The point I wanted to make was that doing slow deliberate reps with high jumps and soft catches is definitely a way to do leg blasters that will emphasize the strength domain of the exercise. Doing faster reps with a bit less height and emphasis on form will emphasize muscular endurance. Doing lots of back to back sets with minimal / no rest will emphasize fatigue resistance, etc.
I wanted to make the broader point that there isn't a "best" way to structure the workout (whether one looks at the structure of the individual reps, the rep/set scheme, the rest time, whatever)… just ones that will emphasize different things. Aligning your goals with how you do the exercise should be the recommendation (maybe, I'd actually recommend you do it in whatever way you find fulfilling to do in order that you do more of it).
All the optimizations of speed, height, etc pale in comparison to the actual benefits of just getting out there and doing more, so for the most part I think a lot of this is arguing about minor margins. I have found that telling people "form is super important to never lose" or "you should be doing this exercise exactly this way" leads to people just doing less exercise and that's why I keep trying to push back against it.
In fewer words, "You can't out-science hard training."Quote:

Supposedly, I have a fully torn acl, torn mcl, and fucked medial meniscus all in my right knee. My workouts are without exterior brace support. For me, I’ve found that form and alignment when working out has been important or I experience mild swelling/discomfortable later or acute pain/discomfort while performing a workout activity. With leg blaster stuff, I’ve tweaked my form and tightened the distance between my feet doing jumping lunges. But I’m still starting low and jumping high. I liken it more to a tele stance than a far extending lunge. I still feel like I’m getting benefits from the exercise.
It doesn't seem like it should need to be clearly stated that the principle "form breakdown isn't a big problem" shouldn't be extrapolated to mean "it's fine to do exercises with garbage form when you're lacking ligaments that provide joint stabilization"
Sorry. That’s not what I was trying to say. I was mainly sharing my experience.
One particular exercise, Bulgarian split squat, it’s only a slight tweak of alignment between discomfort and feeling fine. I visualize/focus pressing/weighting focus on the ball of my big toe and my heel.
I am putting the weight where it should be - where the skis and boots are.Quote:

6 minis today.
Was easier than the initial set of 5!
I like to do a ton of knee risers or whatever people call them..sometimes w the ankle weights. Builds abdomen strength a bit too.
Having the muscle memory to lift your skis nimbly, feels as important. Good training for the sidestepping up to the easy access ridgelines.
+ sit ups! having strong hips and core really compensate for my lack of quad strength last 2 seasons
Training hip flexors and tibialis anterior is the hot new thing in athletic performance and knee health from the little i see on social media. Makes sense, most people (myself included) have way undertrained hip flexors and those are actually the first thing to go usually on the first tour of the year. I've always like hanging leg/knee raises for the ab and hip flexor component, and when no one else was around in the gym i might have even pretended to ski a sweet mogul run complete with hitting jumps and tweaking/shiftying out in the air. Honestly, any kind of ab training where you can get close to gymnast levels of slow, full range movement in complete control is gonna be hugely helpful and make you feel like a super athlete.Quote:

Bad form can cause the intended muscles groups to not get worked. Squats again - many middle aged folks don't fire their glutes very well. Squats and other exercises can remedy that, but not if you are using form that bypasses the glutes.
But otherwise, totally agree. When I'm at my speed/skill limit on skis I'm hitting movement patterns that are pretty darn suboptimal. That's sort've part of the deal. Same with any ball sport. And that' variation of movement is actually super healthy for your body. It's one of the reasons that using different weights and motions to train a muscle group works so well - variation is good. Let's just use squats again as an example - back bar, front bar, trap bar, kettlebell, heels elevated, body weight etc - yer gonna do them all slightly differently. Nothing bad about that.
Finally, I totally agree with whoever said that it's way more important to do stuff than to do stuff "right." It's like arguing about bike seat weight when you have a 20 pound gut. So many of the folks that argue about being perfect with exercises are barely training (not here, just generally.)
Just do stuff. Do it a lot. Use all the parts of your body. Lift heavy stuff with both your arms and legs. Do stuff intensely and be uncomfortable doing it and do stuff where you are comfortable. Do some of the stuff very quickly, and do some of the stuff for a long time. Do stuff that makes you unstable. And get good rest both mentally and physically.
You do that and not only will you be in a fantastic place physically, but you will be fitter than 99% of the population.
