I don't think there's any exercise better than the stair climber

I bought this last December and have been doing it for 30 minutes every day.
Since I started this, no matter how many refined carbohydrates I eat,
my blood sugar levels return to completely normal after 2 hours.
I think I understand why doctors recommend this exercise so strongly.
I don't have diabetes, but even so,
I can definitely feel my body changing.
When I wake up in the morning,
my body feels very light. For those wondering what kind of exercise to do,
try the stair climber.
Even if I stand all day, my legs don't ache.
