Unlike when I was in the Corps, the Corps has Height/Weight and PT standards for all cadets today. And we are strictly enforcing those policies. Many cadets have not been allowed to return to the Corps because they failed to meet Ht/Wt or PT standards.
Our Ht/Wt and PT standards mirror those of the military, so we have a very good reference point to use. While no system is perfect (I served for 31 years, and still saw soldiers, NCOs, and officers that I thought looked "heavy" despite our Ht/Wt and PT standards), its a good system that is fairly enforced by Corps leadership, our ROTC programs, and our Cadet Training Officers (CTOs).
Just for what its worth, Retired Marine General Mattis attended a review in his honor this year while he was here as a guest speaker for SCONA, and he commented to me that he didn't see a lot of fat cadets in the ranks as they marched by. He was very complimentary of the way our cadets looked, and I had to say that I agreed with him. I felt the same way at Final Review - I saw very few "heavy" cadets marching by that day - proof to me that our Ht/Wt and PT programs are having a positive effect.
We aren't perfect, and we still have a lot of work to do, but we're making good progress throughout the Corps, and I am pleased with how we are maintaining the standards and making a big difference in many of these young peoples' lives - many of whom have never done PT their entire lives.
Hope this answers your question concerning Ht/Wt standards for the Corps. We have them, they are enforced, and they are having a positive impact across the Corps.
Thanks for your support of our Corps! Gig 'em!
