Hi all , so ive recently taking up a new hobby of walking. I have been loving exploring new trails and walks up and down the country and have been moving on to hill walling. My problem is I can walk for hours on flat but as soon as there is an incline I cant breathe, I feel like I can't get enough oxygen in my body. My husband was shocked at how bad I was and moaned everytime I stopped even though I pushed through and made it to the top each time we've done a big hill. I've tried breathing just through my mouth. I've tried in in through the nose out from my mouth etc. I really enjoy hill walking and feel a massive sense of accomplishment when I finally get there so I don't want to give up.
any advice would be helpful
