Quoting RyderOCZ

Lower my body fat percentage, it is way out of control. That is the primary goal here. A little bulking up / strength increase in the arms wouldn't bother me either, but I really need to get the "spare tire" under control.

Do you know what your percentage is now? Your treadmill workout sounds weak to be honest dude. 3.5mph is like a walking cool down pace. 110bpm on your heart rate isn't much higher than resting for most people. Mine has shot up over 200 after a sprint with an interval workout. You need to work or your benefits will be minimal.

Do you have a high school or college near you? Their track's are typically open to the public assuming its outdoor. We had an indoor and outdoor track at the university I went to that I would use depending on the weather before I was even enrolled there. Jog as much of a full lap as you can and use that as your baseline. Break it down into fractions. If you can run half a 1/4 mile track then run that and recover for the second half, then run the next half, so you're alternating between running 1/8th a mile and walking 1/8th. Do that for a week then try running 3/4ths the way around and walking. Work yourself up adding distance every week till you're jogging/running more and more of it.

If you aren't crazy about running with other people around go late at night or earlier in the morning and work on it. I don't know what you're eating but my guess is that you aren't eating enough and you've probably strangled your metabolism. Eat 5 or 6 meals a day and split up your total calorie intake among them. The farther out of shape you are the more you can accomplish at the same time. For example you can probably drop fat and add muscle at this point at the same time. Unfortunately this is also the paradox of bodybuilding. The better shape you get into the less you can multitask. As you get into better shape your body holds onto your fat a lot tighter. Eventually you'll get to the point where if you want to add muscle you have to accept that you're going to add some fat at the same time and likewise if you want to drop your bodyfat percentage down you're going to lose some strength doing it.

Personally I find the bulking trickier than the cutting. Its easy to pack on some muscle the trick is trying not to pick up a bunch of fat in doing so. On the other hand I find it easy to maintain what muscle you have while cutting provided you work out consistently and are religious about your protein intake. I can't stress working out in the gym with free weights if you want to lose weight and shape up. I believe its something like 500 calories a day for every 10lbs of muscle you add. If you add 10lbs of lean mass to your frame and you want to drop your intake by 1000 calories you only have to cut 500 from your diet and your muscle will burn the rest with your inflated basal metabolic rate.

Combine that with something like carb cycling and you'll see some pretty incredible results pretty quickly. I could ramble on this forever its easier to answer specific questions with regard to nutrition or fitness.

**Edited to add - Yes 4 intervals and being completed toasted and out of breath after 5-10 minutes of hard running will do more for you than a 25 minute walk many times over. **
