No reason the OP should be doing an intermediate program at this time. Off the couch, the novice effect will allow him to add weight to the bar every workout for weeks or months. I’ve been an intermediate for years and I am still able to run Novice Linear Progression for short periods when coming back from trips, illness, down time etc.
an intermediate program uses periodization because the trainee can no longer recover from one workout to the next. For example, Wendler 5-3-1 adds 10# to your squat once every 3 weeks because an intermediate trainee requires much more stress and recovery time. The OP should be able to add 5# per workout, 3x a week for a total of 45# for the same 3 week period and he should be able to continue that progress for a decent amount of time. There is 0 reason to do more complex programming or unnecessary volume than an individual needs to progress forward. If there is a more effective Novice (novice does not mean that you don’t know anything, it simply means that you untrained or detrained) program than Starting Strength Linear Progression, I am unaware of it. Strong Lifts has unnecessary volume for a novice. Take advantage of the simplicity of those novice gains while you have the opportunity. The goal is not to do the most complex or crazy program you can find or to be so sore you can’t walk, or to try and turn the gym into the mountains, the goal is to get your body the strongest you possibly can in the shortest amount of time and a barbell with 4-5 movements and a proven program is the most effective and efficient way to do that.
I’ve said this before on here but mountain hunting is not rocket science. Get your body strong and then get in shape for hiking with a pack. That’s it -very little skill involved so don’t make it harder than it needs to be.
