I'm looking for opinions on my current push/pull split. I'm in my mid-40's, ectomorophic, '6, 0", 170 lbs. I've been lifting for about 6 months, showing some gains but perhaps not as much as I'd like. My objective, besides obviously staying in good overall shape, is to gain lean muscle mass and to keep it where it needs to be.
Seated Cable Row
Abs (crunches, Swiss ball, etc.)
Two sets of each of the above exercises, 8-12 reps, increasing the weight when I can comfortably accomplish two sets of 12. I use mostly dumbbells, but rotate equivalent barbell and cable (home gym) exercises into the program for variety, such as DB rows instead of the seated cable rows. Cardio twice per week, either recumbent bike or brisk walk for 20-30 minutes.
I'm on the 5 to 6 meals a day plan, and supplement with whey protein, multivitamins, and flax oil. Is creatine going to do me any good, or should I not even consider it?
