If you are an experianced lifter, you know this is a ludicrous idea and recipe for wasted time. # of years in the gym doesn't make you an experianced lifter. It's continued education, kowledge, experiance, nutrition, gains and losses, continued education, continued education. And did I say ... CONTINUED EDUCATION. Which means, if you were experianced and educated you would know better.
Train the same.
1 day upper 1 day lower
5 days of recovery is fine. Your not gonna see any losses in that 5 days. And if you have been lifting 20+ years, you'd know that, that amount of gym time will destroy your gains and what you have. And if you have been training 20+ years. My guess is your 35+ yrs of age. So you don't have the recovery capability of a 16-18 yr. So 5 days is fine.
Then again.... I don;t know your goals, or training plan. I only assume its intense. But if its mild and you want endurance, it "could" work. But I doubt many T-Nation members are endurance atheletes?
