  1. The spiral planks require good shoulder integrity and health. My left shoulder is slightly compromised after 51 years of serious weight training, and while it works fine most of the time with most exercises, it can occasionally feel kind of strange, as if something is wrong. Because of this, these days I usually avoid any rapid movements involving the deltoid complex that have the potential to put the shoulder in a potentially compromised situation – generally I do slow and controlled exercises, whereas the spiral plank is fast, and due to the multi-plane transitions required of the shoulders, could cause injury. Of course, this is just my personal situation, and I am sure most younger trainees will have shoulders that are not susceptible to what I am describing here. This is a great HIIT workout Dan, and doing it outside in the fresh air makes it even better! Live long and finish strong!
