>TFW legs and lower back literally get tired from doing cardio

>>37807726
Your legs are weak because you've never used them. You will get stronger.

>>37807740
But should they even hurt from this low intensity?

Should I just give up or push through? Will they adapt?

>>37807756
push through you defeatist swine

only children and the french quit

>>37807766
Will it get better or am I only hurting myself?

T. fatass from r9k

I bet you don't even train though

>>37807775
If you want to play safe you can try suspending cardio while you strengthen your legs a bit. Isolate quads, etc with isometrics for even more knee and other articulation strengthening before impact work like running

I'm using the stairclimber

How long before cardio gains?
For three weeks, nearly every day I ran 4k and by the end of it I didn't feel as if I'd gotten any better/fitter at it. It's putting me off start again because it feels like a lot of hard work, at something I really fucking hate, and I don't seem to get any better at it.

It's like lifting. Set goals. Try to run 4k in a certain amount of time. Try to be a little faster every time you run. Blindly running 4k makes no sense. It's like lifting the same amount of weigth every day and never increasing the amount you lift.

nvm found it with a google search

>>37807726
If you are running or bike yes your legs will get tired and you will build some muscle.

>>37807804
No just do your cardio and your legs will get used to it

It hits my quads pretty hard desu

>>37808635
thats cos u got weak quads, the other guy probably squats so has weaker (relatively) calves

>>37808655
i squat too... but i am weak

I can run sprint and run long distances really well, but my squata are weak as shit. My friend hates cardio but lowes lower body training. Not sure which I prefer.

>>37808655
Funny enough my calves are really big but the stair climber is still really challanging for them.
