I've been contemplating a treadmill from eBay... It's not too expensive and is mechanical (no electric). It has an incline which is supposed to better mimic outdoors or burn the same calories or something...
I love love going out though. It's just those few times when the weather is truly terrible that I don't want to miss out on my daily walk/run. But I dont know if it will be too monotonous?
Outside I love the different skies, the trees, the birds. I love taking big gulps of fresh air into my lungs as I push myself! I usually just focus on the tarmac in front of my feet but then look up when I reach my half way point and love the view before turning to go home. And then knowing you are heading home is a reward too!
The treadmill will have none of those things so I just don't know.... I do love putting my music on through my headphones so maybe I can focus enough on that?
I own an exercise bike but it's very tedious and I've even tried watching a video of moving scenery but makes me feel sick lol. It's very hard to push yourself for more than 20 mins! Unlike outdoors when you simply have to keep going to get back home!
But in the past I have used and liked treadmills in the gym?
