My blood pressure is going down since I started exercising and losing weight

I went to the hospital the day before yesterday to pick up my prescription,
and when they measured my blood pressure,
my systolic pressure was 123 without taking any medication.
It's still a bit high, but it has improved a little
since I started exercising about 5 days a week ㅠㅠ
Still, I'm continuing my blood pressure medication..
