Get him doing farmer's walks with a weighted vest(if available), this threw my conditioning up pretty quick. Other lifts: DB snatch, weighted pullups(he will be doing pretty much everything in full call-out gear), bench(only since that is his goal, it won't do much for the comp), weighted dips, squats. One thing that will really send his conditioning throught he roof would be doing the Bear in an EDT zone. And get him doing various sprint intervals-40 yd repeats, band sprints, ladder sprints, etc. after each lifting session. Repeats-sprint 40, jog back, repeat. Band sprints, you need big bands like Westside uses and a partner. Both of you get inside the band, your partner in back. You will sprint a distance(pre-determined), with you partner sitting back in the band and giving resistance. When you reach the other end, the partner sprints while you sit back and resist. You are trying to jog while he is sprinting, timing your footstrikes with his to keep tension on the band. Ladder- football field works best, but any 100yd area will work. You need the 100 marked each 10. You will sprint the full 100 and back, rest 60 seconds. Sprint 90 and back, rest 60. Repeat all the way down to 10 and back, you will reduce your rest time every few sprints.
power clean, either from floor or from hang, followed by front squat(bar in rack position from clean), push press to back squat, push press to front, lower weight. Repeat.
This should be done as fluid as possible, continuously go from movement to movement.
For the EDT Zone, set a timer at 20 minutes, and he does as many reps(full set front to back to front is one rep) in that 20 min as possible. Number of reps done at a time are up to him, so are rest periods. The goal is each time he does the Bear Zone, he tries to beat his previous performance, either by increasing weight or by increasing reps.
Just some of my thoughts. SWAT comps are like firefighter comps, extremely physical and dictated by the clock. Some of the stuff will be a short sprint or carry followed by a room entry, where they will be scored on time and accuracy. He should be doing team practices, if so hopefully they are doing stress fires, i.e., running short O-course in full gear, then running up on line to fire at a target for score and time.
