Francisco:
I read up on "anerobic threshold":
...
Your anaerobic threshold is improved by any type of aerobic exercise, such as walking, jogging, cycling, aerobic dance, stair climbing, etc. The more time and intensity you add, the greater the effect on your anaerobic threshold. Another way to "push" your anaerobic threshold is to exercise above it for several short periods of time during your workout. For example, increase your exercise intensity for one minute intervals several times throughout your exercise session.
How do you know if you're above your threshold for that one minute period? The intensity should be enough to elevate your rate of breathing and to fatigue you to the point that you are very ready to slow down after that minute. Of course, the intensity of your intervals should be decreased if you have not been exercising on a regular basis. As always, be sure to check with your doctor before making any changes in your level of activity.
Elevating the point at which you reach your anaerobic threshold can do wonders for your overall feeling of well-being, and it can significantly increase the amount of "energy" you have during the day and during your exercise sessions. Get movin'!..

So with what I'm reading from that.. it looks like alternating sprinting (or working up to that HIIT stuff) once a week as quagmire suggested will be ideal to attain what your recommending.
Quagmire
You didn't mention sprinting per say.. Is that still acceptable or do you rather recommend going hard on the equipment you listed instead of the treadmill?
Also yeah my threshold I'm sure will be rather low to start.. but honestly it would be nice to get some extra energy. I guess if/when I add this I'll keep monitoring my muscle gains carefully to see if it effects me too negatively.
Thanks.
