I should amend my comment to say that even if ramaswamy doesn’t know it, he’s not really being honest though. The federal govt isn’t that inefficient. And his purpose isn’t to make it more efficient; it’s to degrade and destroy federal institution function.
Even the ghoul Larry Summers said attacking payroll is a losing battle, as it accounts for like 15% of the govt ledger, and that ledger is made of fun money to begin with. Sigh.
Former rower also, co-sign all of this. Form/technique is key, and contrary to most people’s assumptions, the machine is, like you said about a stable core and leg power with arms doing not much till the end of stroke. Definitely worth watching stuff to get the form down, most people use the machines incorrectly.
Nice thing is the difficulty is mostly self driven—and comes down to split times. I’ve had erg sessions where I barely broke a sweat. But we also had some erg races… where we all ended up puking haha. Do not miss that.
Shouldn’t be tough on knees unless they have significant mobility issues with bending the joint.
I would search around a bit on craigslist or Facebook marketplace or whatever and see if you can find a second hand concept II air machine. There should be a fair few of those in circulation.
Every time I’ve bought sub 200 dollar home excersize machines off amazon I’ve been disappointed (3 times).
Also this just could be my hours spent on the machine back in the day, but… it can be pretty boring. Unlike a stationary bike, your hands are also engaged all the time which is good for workout, not means you’re not playing with tablets or books etc.
