Evidently you have no clue about cycling training.
Do you mean stabilisers?
I have been thinking about getting a power meter for a while as have … I have been thinking about getting a power meter for a while as have heard they are a great way to become a better cyclist by being able to pace yourself etc sounds like you really need to know how to use one to get the best out of them though!This is the cheapest i have seen one and certainly very tempting although its still a big investment! Decisions decisions :P
It'll completely change your cycling. Cycling is more fun actually with one oddly. I always thought getting a power meter would ruin it for me, but it's been completely the opposite.
As for knowing what to do. You need to do some testing. Indoor or outdoor FTP test or a really hard long ride full on with the Garmin on auto FTP calculation.
After you do that, then the world is yours to conquer. You can now go out for a ride and know what power to ride at for how long. After a while, you naturally start getting really smart about how you spend your power, and your power curve on Strava fills out (you probably don't even look at that before) you can know exactly how long you can hold so many watts for 3 min, 5min, 30min etc etc.
Which now means you can target your best times on certain roads. Just go out and hit that number for whatever minutes. Heart rate work just isn't the same, because your heart doesn't respond the same way as a strain gauge. The heart needs time to warm up, so riding to heart rate is only really useful on some longish efforts in certain conditions.
Honestly, your fitness on the bike will start to rocket, cos you'll end up doing workouts to power and actually do real training. Everything else is guesswork without power. You cannot get definite consistent progression the same way without it.
If you love cycling, save up, buy a power meter. In the meantime, while saving, just read up on power and training and stuff like that. Learn the basics, maybe you're way past that already. There isn't really much to know that's the thing.
In terms of technical knowledge, you just jump on bike and ride it and there's your power on your Garmin. When you first fit the PM, you go to settings and click calibrate and spin the pedals once or something silly. Really nothing there that will mess with you, it's all designed to be user friendly.
