Oh okay but the problem with moving fast against the resistance is that I tire myself out too fast though and cannot continue for long enough to get the heart going near as far compared to moving fast without resistance like I was able to with jogging, before my knees got bad. So how do you keep the resistance from tiring you out too soon, before you can get the heart up near as a effectively, compared to moving fast with less resistance?
The fact that it tires you out so soon shows you lack stamina. You lack stamina from not working against resistance. You gain stamina by keeping doing the thing you can't do. Reduce the weight SOME, but not ENTRIELY. It HAS to be work or isn't not doing anything.
The reason jogging works isn't just cos "you're moving fast" - and frankly, jogging isn't all that "fast", which further demonstrates a lack of stamina - jogging works because your body IS the weight. Your legs are supporting you, and moving you up and down, and forwards as you jog - you are moving weight - your own weight. On a bicycle or floating in a pool, you are NOT supporting your own weight - the bike is, your buoyancy is - so you re NOT getting the resistance benefit out of it. The reason working out in a pool is good is cos it puts resistance on EVERYthing.
Moving fast might get the heart moving faster, but that's just what the body does when you move fast. Improvement comes from overcoming the difficulty, not from avoiding it.
