Alright, sorry for the long post:
History - 20 years old - I have been doing moderate cardio for more than a year and have suceeded in losing about 55 pounds of bodyfat. 270 to 215, it was tough as shit but I really wanted to change my life. I just recently got active in lifting serious weights to fill out some of the loose skin and also just learned about HIIT cardio about a month ago.
Routine - Semi HIIT running every day except wednsday for 20 minutes with about 4-6 minutes being absolute sprints (2nd and 4th laps of a 5 lap run) followed by my weight routine directly afterwards (the 15 minutes it takes for me to walk from the park to the gym) Weights: mon-chest/tris, tues-legs, wed-rest, thurs-shoulders, fri-back/bi's.
-I have been on this routine for about 3 weeks feeling great until BAM- woke up thursday morning dead sick with flu (keep in mind I get sick like once every 2 years or so, no joke) so basically:
1) Is there any such thing as overtraining the cardiovascular system? Is this what happened? I run seriously 6 days a week(the only reason I take off wednsdays is because I lift legs on tuesday)
2) Cardio bad before weightlifting? (this one is tough for me - I love to drink water while lifting its just something to do between sets kindof a habit, if I go do cardio afterwards with like a half gallon of water on board I am going to lose it for sure)
3) Does this routine generally look halfway descent or are there serious flaws like dont weightlift and HIIT at the same time?
Conclusion - the reason I do this is because I still really want to lose the last 10 -12% of body fat to get at least somewhat "ripped"( I was way above 30% and am guessing now around 20%) Also I really never knew how much I enjoy weightlifting until I started a few months ago, I am literally twice as stong in all my lifts and really have lost some serious fat too. Basically I dont think I could psychologically work so hard on the cardio without the weights - I almost look foreward to lifting while I am running...strange?
Sorry again for such a long post but it is my first and I had a lot of questions...
