[quote name='DrFoo']OK I have a couple of questions for you guys. What are the advantages of treadmills vs elliptical machines vs stationary bikes vs jogging/running? I found out I have a gym near me that's free for students with all 3 machines and a nice track, and from switching from jogging to the bike for one day it felt like jogging was almost exclusively hitting the calves while biking was almost all thighs.
Also, what do you guys recommend for a running schedule for someone who wants overall fitness (lose fat, gain muscle/speed/endurance)? I was thinking of running hard (interval training or something similar to help build up the muscle/speed) about 3 days a week on days I'm not working out (I usually work out Tuesday/Thursday/Sunday) and doing lighter long distance stuff on as many of the others days as I can to burn calories, running about 30 minutes each time. I know you need to give your muscles time to repair, but I'm not sure if that's too much or not.[/quote]
Your preference as to which machine you would like to use will depend on how you feel on certain days and possibly even your current body composition. For me, I find it extremely difficult to stay in one place while I am exercising because I feel I am not getting anything done. However, if it is cold and rainy outside, I find the bike to be the most enjoyable because of the low impact. I also find the low impact helpful because of my body size (I'm about 6'5, 215 lbs.), so distance running really does a number on
my knees.
Interval training is a great supplement to your weight training because it works your body anaerobically which is the best for burning fat in the shortest time, and it also helps to develop your fast twitch, white muscle fibers which are essential for moving heavy weights in the weight room.
As far as the repair and recovery, you should be OK with some form of cardio every day. The only recommendation I will make is not to perform all out sprinting intervals the day before, the day of or the day after a heavy leg training session, as you will find it very difficult to push yourself to the limit.
