[Unanswered]  Would in real life physical conditioning help me with my beys power?

I have been working out for a long time and I've been ripping harder and I've seen my power get stronger! Like a lot, and I train with my bey around 2-3 hours a day to perfect my ripping technique!
Some would, some wouldn't. Blading isn't a full body workout like the anime would have you believe but arm and chest strength definitely play a part in your launch.
It works for me and my shot power nation wide is 11279

I mean my rank is 11279 and my shot power is 1660
Short answer; no, not really. In the anime, it's both a physical and mental sport and the launchers are very likely made to much tougher winder/gyro standards, to need more muscle power in launches. Whereas a TT or Hasbro launcher, yank too hard on a string launcher and you'll most likely break it! They are made for small kids afterall.
No. The gears of launchers have limits before they start skipping.
In fact, launching too hard can be self defeating (Most Burst Defense and Stamina combinations)
Maybe strength exercises (lifting weights, push ups, etc.) could improve your launch power.

Just remember to keep control of your launch
Well, the answer is both a yes and a no. Yes, because having stronger launches does help increase of the beyblades spin, however, it is to a certain extent. The reason why increasing your strength only goes so far is due to a few factors: for one, and probably the biggest reason why is because these launchers have a limit to how much it could take before the gears will wear or break, they aren't the most durable things in the world. Another reason is that these winders length can only take you so far. Lastly, and especially in Bursts case, the tops themselves don't sustain the spin power for very long no matter how crazy your launches are, and some Burst beyblades benefit from a softer launch to decrease chances of Bursting.

The anime normally encourages this, but it's seen as a sport with the similar amount of intensity as something like football, with characters doing really pointless training such as running with tires. It's somewhat understandable with the classic trilogy or the metal saga as they need to harness their energies into the battle and the battles are far more intense and dangerous, but with Burst, it makes no sense. Heck, even with all that, Burst seems aware of the launchers limits, Xhaka being the best example as he's broken launchers a few times.

So my answer should really be changed to a "Yes, but mostly no".
Depends. If your stronger you can pull Light launchers harder. but in ends its more about how quickly you pull winder/string then how strong you do
