Legs tire out faster than lungs during cardio

[Ivankannan]

My legs start to burn even before I am panting for air (20mins HIIT). Does this happen to everyone? Today was the worst. My legs burnt so much that I couldn't walk for sometime. I don't get this feeling when I squat.

yeah i have the same problem...i NEVER tire out of any cardio..any machine..or any sport..cause my lungs cant take it...when it comes to sports i find it easier to keep going cause im having fun so the burn in my legs doesnt bother me so much...but if im on a machine doing HIIT...the burn in my legs becomes intolerable..sucks

Your VO2 Max is higher than your lactic threshold.. both are basically genetically predertimined... with slight adaptations from training.

good info..wouldnt have thought it was a genetic trait

This. You can increase lactic threshold by doing glycolysis-based training (i.e. 800m runs or 100m sprint intervals with very short rest times).

Any tips to reduce the burn? Practice makes it perfect (or reduces the burn)?

same here, plus i have the fat guy factor lol.

Oh thanks, you just answered what I asked above. I am right now doing that: run as fast as possible for 45secs (9 to 10mph) and the walk for 1 min (3mph). My cardio always sucked and I have started to like it (like going faster/longer everytime I go in).

This would sound ridiculous, but is there a way to do cardio that doesn't involve legs?? I hear P90X does that but I dont' want to do P90X right now.

u could try the rowing machine..its the only form of cardio i can think off that involves primarily the upper body..or swimming doggy style for laps around the pool lol

Oh yeah! That should be helpful on the day I workout my legs.

Basically Lactate Threshold refers to the intensity you can work to before you begin to accumulate lactate faster than you can clear it. So theoretically, if you train below your lactate threshold, you should be able to train almost indefinitely without acidification of the blood and tissues. Thus ATP and Muscle damage would be your limiting factors (if your VO2 max is higher than your lactate threshold)

I'm by no means an expert in lactate threshold training. I only know that adaptations can be made, but it is largely genetically predetermined. I did a quick search on it, and they basically say increasing the volume of aerobic training is the best way to increase lactate threshold... so what does that mean, I guess? They describe it as "if your currently training 100 minutes daily, and want to be able to train for 200 minutes, to increase the amount of time per training session gradually... OK duh... that sounds simple enough, but you're talking about getting burnt out on hiit, which makes sense, since sprinting is anaerobic, and lactate will accumulate faster. My guess would be that you would want to find a training intensity just below your lactate threshold (through trial and error... it will probably be a moderate to fast jog, I would assume), and work at that for a period of time, until it becomes difficult... then the next time you do it, you'd do it a little longer and so on.

That's just what I take away from the couple things I just read, but again, I'm by no means an expert in this.

Thanks man, let me see how whether it is improving after a month. But I totally love the burn (in hindsight).

Boxing. You think its tiring but until you do it you have no idea. Will help develop some stregnth in your shoulders and tris (when holding the concentration mits) too.
