Just see Skipper asked this on Insta and thought it was quite a good question.
his answer was lactate monitor as no one knows what to do with the data; personally I think its deeper than that, many amateurs may not even get meaningful data in the first place.
For me; Zen8, you aren’t in a real swimming position as you are “flat”, its just allowing you to lay on your front whilst pulling some bands. How about just buy some bands/stretch cords and a swiss ball and get far more use from them as they are more versatile.
Expensive to buy
Expensive ongoing subscription
Wear out quickly and need replacing
Don’t really add anything that the already existing pace clock/sports watch don’t ***
There are more useless things, but these are contender as so highly rated/promoted/sponsored.
** I’ve never actually worn them and don’t know if the technique features are any good. That may be a redeeming feature but wasn’t letting that get in the way of a rant.
They are obviously a benefit to most but the hype is overwhelming. In a five hour marathon they might save me 12 minutes. Big whoop. Or I could have five pairs of decent running shoes to rotate through weekly training.
Nah, I think they’re good. Motivating to see things like weekly distance, average pace, can use them for intervals all of which make you a better athlete.
