I've battled with asthma for as long as I can remember. Mine also manifested in coughing fits after strong exertion. When I got older I was able to forgo the inhaler but poor diet and poor exercise regimen left me quite a mess. When I picked activity back up with primal eating and exercise I also bought a bike and started riding that around. Since I've been primal I have much fewer coughing fits and I am slowly improving.
