I live in an apartment; the lifts are located in the middle of the building, with the corridor circling it. So I rode around that, concentrating on improving my fakie out of 180s & other tricks, hop to wall, flatland tricks which feels really refreshing, and practice tricks with my 'weaker' foot forward; nvr really rode with my left in front, always rotate to the right doing 180 360 or even up the ramp, now I'm learning the other way round with the weaker foot fwd. Actually I started this late last year & I have better control of my bike now, but there's just lots of room for improvements.
Anyway was only able to do that in the 1st few weeks of the MCO (movement control order they call it here) when control was a lot lean, haven't been riding since the 1st week of April after they tightened that. I live in the capital so the risk is very real, more so since I'm asthmatic & we hv sporadic cases here. If you are out riding, kill it & stay safe!
