coupla questions

Will doing cardio negate the effects of doing a leg workout? i.e. I just did a low rep quad workout today, but then ended up biking for half an hour (extremely high rep, low weight workout). Will that hinder muscle building?

2nd - During cardio, is not hitting your 70 - 80 percent target heart rate that important? I got bored as hell with running, so lately I've been biking, but I've noticed it's hard to keep in the target range while biking, I usually end up more like 60 - 65 percent of max heart rate. I've heard that under 70% of your max heart rate is no longer aerobic. I don't wanna do too much aerobics anyway cuz I don't wanna lower my metabolism, but I like to do some anyway.

3rd - Right now I'm cutting fat (lost 25 lbs so far) and eating around 1800 cals/day (200 g's protein, little over 200 g's of carbs, very little fat). I've been working out to avoid losing muscle along with the fat. I'm assuming I will make little or no muscle gains during this... will I lose any? I haven't noticed much muscle change so far except after the first few weeks I could see better definition, but I have no way of really telling if I have gained or lost muscle (cuz simply losing fat will also improve defintion). Anyway, I'm just worried that even tho I'm working out I still may be losing muscle... lemme know whatcha think, thnx.

Not significantly, if done in moderation.

No. In fact, if you're trying to lose weight, you'll burn more calories with interval training, which takes much less time and definitely doesn't keep you in the so-called "fat-burning" range.

It depends. Some people even gain muscle while losing fat, but you shouldn't count on it. You're doing the right thing by continuing to lift. Also, aiming for no more than 1-2lbs of weight loss a week (approx. 12x your bodyweight in calories a day) will help you keep your muscle. More than that and you're much more likely to lose muscle.

Congrats on your progress so far, and good luck! :aright:

True... I'm not a bodybuilder, nor do I claim to be one, nor do I want monstrous legs. On top of that I can't do real heavy weight on squats for fear of tearing a tendon in my knee that I tore 3 years ago & never quite healed properly... so at any rate, I still do a lil cardio after my workouts

btw... what the hell is the deal with the "target heart rate", and if it is such bs, why does everyone talk about it?

True, I misread the original post. I was thinking more of doing cardio on different days.

I don't think it would impact your workout much even if you did the cardio right after, unless you did it for so long that you neglected your post-workout nutrition. But like elites said, cardio may not be the first thing you want to do after a heavy leg workout!

BTW, deep squats (below parallel) are safer for your knees than, for example, leg extensions or smith machine squats. That's because your hamstrings stabilize the knee joint when squatting.

actually I don't think I'm gonna do it anymore after a leg workout... it made for weak cardio

at first I was afraid to go deep (more than 90 degrees or so) cuz of slight pain in my knee tendon, but I did it one time and it didn't hurt when I go deep, so I do that now. I've heard of people building muscle too fast & tearing tendons, and since I already have a tendon problem I don't wanna do this... I'm assuming if I do higher rep/lower weight squats that over time the tendon will become stronger & I won't do damage to it... is that correct?

From what I've read, that is a good approach to take. You might also try front squats; once you get past the difficulty of balancing the bar in front of you, you can go deep very easily. However, please do take my advice with caution as I'm not a doctor and don't know the details of your injury. :)

You ain't kiddin... My legs shake uncontrolably after my leg routine... I never do cardio after a leg workout...

I will do 15 minute warm up on the tread mill before I do legs... But I will never do it after...

I read that doing cardio after a leg workout promotes burning calories... But I do not know. All stories in the mags tend to get negated by other articles... :cool:

It does promote burning calories, but at the expense of muscle. Depleting glycogen from the body does help burn fat faster - but I would not recommend it on a leg day.

If you are thinking about cardio - you will hold back on legs. If you dont hold back - you will not be able to do cardio.
