well I am a diabetic, so the potassium thing may be valid. When I went to the hospital they had me taking potassium pills often. I make sure to have a banana a day, lol like it's going to rectify everything. Maybe a MV would help.
My routine... I don't really change it.
Curlbar, dumbell curl, pull ups, hammer curl
Tricep pull downs with rope, dips, one arm pull downs with palm down/up
Shoulder Press, Shrugs, Lateral Raise
next day
Incline, Decline, Bench, Cable Flys
Lat pulldown (wide), Lat pulldown (narrow), Mid row, Back Fly, That thing where you lay down on an inclined bench and pull weight up (dunno what it's called)
Leg Press, Calf raise, Leg extension
Thats what I do.. just alternate between the two.
