Good for you bro....I love to hear success stories like this where
folks have lost a good amount of weight, and are dedicated to
reaching their goals. So, now its time to tighten up and see
that six pack, right? I would suggest working your abs at
least twice per week, once using resistance training, the other with
ie. resistance training for abs would incorporate using weights or
resistance on a machine to actually build the ab muscles. They
too are just like the other muscles that we work out...chest,
biceps, legs, etc... without building them it will just be a flat
ie. higher rep training for abs is more less doing as many reps as
you can without any resistance. This should help out with
burning off any extra calories and aiding in the burning off of
excess fat from around the midsection.
I would just follow your workout program as outlined, since its more
less the same principle.
The coffee most likely wouldn't be a factor since the caffeine
actually will help out with raising your metabolism slightly...but
if you can, try and avoid using any sweeteners...try and use skim
milk or something. Although the sweetener is not a factor much
with such a low amount of sugar....its the other artificial stuff
that's not that good for you.
A regular sized cup of coffee contains approximately 100 mg of
caffeine (which will vary with bean type, length of brewing, etc),
so caution is advised when taking doses of caffeine that are much
higher than this.
Best of luck to you, and keep me posted on your results.
