You have probably discovered that it is quite easy to do a 125% run in STEPN. This is the trick you do as you start your session with a full energy cap and start 30 minutes (for example) before you are supposed to receive a new energy boost. By the time the new energy arrives, you have already used at least 25% of your energy, meaning that you will once again have a full energy cap and you have already used 25%. As a result, you will spend 125% of your energy. This is extremely useful if you want to get a chance to get a higher level mystery box. It is also useful right now with all the mystery boxes of low levels. Those will quickly take space among your loot boxes, and it will hinder you from getting new boxes if all four loot box places are taken. That is why it is much better to do big runs with lots of energy in order to get better boxes than to do smaller runs several times a day.
If you don't care about the mystery boxes, then it doesn't really matter, but if you do care about the mystery boxes, this will for sure impact you in one way or another.

There you can also learn more about how you can easily get additional energy by buying higher quality sneakers, but no matter your number of sneakers, the max energy cap is still 20. So, the highest energy you can reach for a single activity is 25 Energy if you use the 125% energy boost.
Of course, I am actually interested in finding out what would happen if I did an 8-hour workout session, would it be possible to do a 150% workout session? I am really curious about that.
