Is this a health weight loss goal?

Start doing some Bicycle Crunches for Abs, Narrow Pull-Ups for Back, Lifting for Biceps, and Pushups for Chest/Pecs. Do this every Monday and Thursday. On Tuesday, Wenesday, and Friday do Aerobics to get you blood flowing. On weekends do a little resting to rebuild your stamina. I've been doing this for quite a while but I'm not impatient or anything.
