Physically it will absolutely put you ahead of the game, and it exposes you to the techniques and standards that you will experience in the water. If you finish the program to a "T" then you will not have to worry about the physical portion just focus on the team and the mental portion at selection.

It is meant to do both. After seeing all the students come through Indoc, I noticed too many people just doing a substandard pushup to try and get grad standards. So I incorporated a lot of exercises in the Get Selected program that have helped me throughout my time as a PJ and instructor to get guys through. There are also days where you will get a gut check, which helps people prepare for the long days so they can figure out nutrition and rest. The workouts I designed use sandbags and a weight vest to help guys increase their numbers.

The criteria for the PAST (Pushups, pullups, situps, and a run) is very similar to the other Special Warfare fields as far as cals go. You can look at that criteria here. My the Pass the PAST program has swimming included, which I would recommend to anyone anyway as an alternative cardio exercise in between run days in order to lessen the impact of running on your legs and prevent shin splints. The only thing the PAST program does not include is rucking which is huge in SERE. So if you can already pass the PAST and would like a bigger challenge you could go for the Get Selected program.
