While it's an interesting question, it would be a very short lived time anyway. VO2 max is the maximum oxygen your body can use at a given (usually fairly intense) activity level. If you exceed this work level, then you are working anaerobically, and the energy pathways for that are short lived at best. Up to VO2 max, your normal readings should be in the ...

For the heartbeat and fat burning the best suggestion from me is to start skipping rope. Just do the basic jump. Skipping rope detailed information On the above page under the title Health Benefits Skipping as exercise Skipping may be used for a cardiovascular workout, similar to jogging or bicycle riding. This aerobic exercise can achieve a "burn ...

I love intervals or circuits for this. Changing up the routine helps me catch my breath, while still working my body. It also fights my biggest problem with running, jogging, biking, walking: Freaking boredom. As Dave said, though, cardio is basically doing stuff vigorously. You know what's vigorous, fun cardio? Dancing. Try to find a retro dance scene, ...

There shouldn't be any adaptation necessary. The few seconds that it takes to ramp up to speed will be offset by the few seconds it takes to slow back down to the walk pace, and is a little bit more of a natural effort than most people that just suddenly go from run to walk or vice versa. So, for the treadmill on your 90 second runs, start the time and ...

For me its all mental, I go with full of energy and excitement to gym. Gym is a place where I have trained my mind to forget all the good/bad things and just complete my sets. I would recommend you to stick to a strict workout plan(a written) and try to finish it before leaving gym.

I would suggest working on intervals. Dave makes a good point in his answer that progress basically requires you to work at a high intensity day after day (with rest days, of course), but it sounds like you're running yourself into the ground on these workouts. Try spacing out shorter runs with periods of walking. When you start to get tired, walk for a ...

I used to go to the gym 2-3 years ago. But now I rarely go, because after a break I can't really do any cardio: after 7-15 minutes at a treadmill I get really tired....I've tried 5-6 times [over the course of a year], but it's always the same thing. Your problem is that you're not giving your body a chance to get better at cardio. One session where you ...

It's a bit difficult to give you a time to aim for if you are alternating between 500 hard / 500 easy. Work up to sustaining consistent effort over 10,000m on a setting 4 (good for giving you a reasonable feeling of what rowing actually is) and with your background anything under 40mins is solid. When my team train we target 1:40min/500m hard then ...

If you spend a few min's performing one of the general fitness assessments, to obtain your approximate VO2max volume, then your heart rate and activity duration should offer enough data to calculate a fairly accurate value, see: Is it possible to measure calorie burn from heart rate alone?

Trying to maintain 80% max HR for 30 minutes is probably going too far - you usually won't reach that unless you're doing something fairly intense. That said, it will be fairly hard to do something "unhealthy" unless you have a heart condition, or try biking for way too long (2+ hrs) without having built up endurance first. Resting and Max heart rate values ...

I have a counter-question for you. If running doesn't work for you, but biking does, why suffer trying to run more than you can? I can't claim that cycling will have a lot of carryover into running (it might initially), but it is a very effective way to get aerobic exercise. Like most physical activities, starting too hard, too quickly can be detrimental ...

Dr Peter Attia is an accomplished athlete who has remarkable athletic endurance accomplishments performed during nutritional ketosis (due to very low carbohydrate intake). His blog is well-researched and well written. I think you'll find his answer to your question is that carbs are not necessary for the type of activity you plan. My personal experience is ...
