I would do something similar to what I did a couple years ago following my back surgery - no barbells; nothing but weight vest, sleds, Prowlers and KB's. I developed a separate training program and several different "standards" to train for. I also used the basic principles and the "20% conditioning" principle - in other words we NEVER TEST, we only train. Vast majority of programs and trendhoppers test and never train.
I dubbed this WaLRUS training, since you are the fat, disgusting cousin of the Navy SeAL. It's meant as a joke so don't start pulling your puds just yet.
It is very comprehensive and I don't want to write the program now. But in general, the standard to reach for the Suburban Commando is:
50 DB squats with 100lb DB
all with 85lbs vest and must be done in 30 minutes. That is one of half-dozen standards I have and what we TRAIN for (again we don't test during training). So develop your standards and develop your training to reach those standards.
