Oh but the reason for this is rooted in how hard you are pushing your heart. Walking? Slightly elevated heart rate above normal. Jogging? 60-70% max heart rate. Cycling will generally put you at about 40%, unless you are going all out. But if you are going all out so your heart rate is 70% of your max, you will last just as long as you do while jogging. (I did a unrigorous test on this at the gym with measuring Calorie burn per minute & heart rate).dunkelfalke wrote:Cycling uses both a bit different muscles and the same muscles in a different way.

You should look into doing weightless squats (but make sure you do them correctly, I used to squat incorrectly and hurt my knee. Then I started doing them correctly and my knees are back up to snuff). When done properly squats strengthen the knees, which counteracts the terrible effects that running causes them.Hoitash wrote:I sympathize. I'm pretty sure at least one of my knees is arthritic at this point. I've found starting slow and limping a bit for a couple strides helps work it out. Apparently Newton was right.
It doesn't seem like anyone responded to this, so I"ll crack at it.Auratus wrote:I am stop running for a long while now but I plan to "rerun" later. So I start push-up using Rin's routine. My push-up is very bad that I can only do that twice and found my arm is tired, and despite I have the motivation to keep doing it. My arms just aren't and I have to give up. I think I recall my mom tells doctor that I have some kind of syndrome that make my arm weak. Can anyone give me some advice how to push-up with this kind of weakness. (I am not asking how to push-up properly. I have read enough of it)
1. Push-ups focus on your chest muscles; your triceps, lats and shoulder are only secondary stabilizing muscles that kick in at points during the push-up movement. if your arms are becoming very tired (and not your shoulder to chest area) I might wonder if you are doing them wrong...
2. That said, are you doing straight push-ups or bent-knees? The latter decreases resistance so it might be easier for you.
3. If none of this is working out I would focus for a month on low-resistance strength building exercises. Get a pair of 10 or 15 lb dumbbell, and do bicep curls and tricep curls, hang from a bar for as long as possible (widen your grip on the bar so you are exercising your lats), lie on the ground and do flies with the dumbbells (with arms extended straight to the sides, bring your hands together, and then lower arms back to the ground while keeping arms straight).
