Yes, I had the single dose Jansen vaccine in May. I also had some residual coughing when exercising or talking emotionally (positive emotions, not shouting). Same thing with strength as with you. No problem with push and pull ups, squats or jumping. It is just that my heart rate goes up faster than usual. E.g. I had to carry a 50 lbs box upstairs and after the second floor I already felt my heart beating. Wouldn't have been an issue before, even if running upstairs with 50 lbs.
