Here is a good set of 25 push presses of the log in between sets of USMC o course runs.

Good timing and teamwork in this video

Some other ideas for teamwork training:

• Walk with the log
• Static hold over the head 1-2 min sets
• Log Squats

Try to keep the log off the ground for 30-45 minutes with walking, moving over obstacles, surf zone, bench press, squats, overhead press, etc...
