Certainly! First of all, the most important thing for having a visible six-pack is low bodyfat, around 8-9%. Having a strong, defined core is also important, so doing ab exercises such as hanging leg raises and ab wheel rollouts is a good idea. Avoid crunches though because those don't do anything.
Read up on hypertrophy as this is how your muscles get bigger. German volume training, vince gironda's 8x8, chad waterbury high frequency training are good plans to look into (all of chad waterbury's workout plans are "cutting edge" imho). I've recently been doing very high number of reps with very low intensity and not going to muscle failure so that I can target the same muscle groups several times a week. Such a workout plan focuses more on muscles getting larger rather than stronger.
Also, if you're looking to cut down on bodyfat in order to see your abs, I would actually use bcaas instead of the whey simply because the goat milk whey likely has calories that your body will use for fuel (ignore that sentence if it doesn't have calories), whereas bcaa's take a different metabolic pathway and go right to your muscles. The point of exercising on an empty stomach is that you're working out with a depleted glycogen supply, which your body will always use up before touching fat storage. If you take in calories before working out then your body will burn through those first before reaching into the fat storage.
After you've finished working out - hopefully your workout was done quickly so you should be very sweaty and have burned a ton of fat calories - wait for a couple hours (at least 2-3) before eating anything. During this time I generally drink almost a gallon of water containing a bunch of bcaas. Your body will continue to burn a shit-ton more fat and will still be primed for building muscle once you spike it with carbs and protein. Be careful to avoid fat though!
Good luck on attaining your fitness goals ;)
