For folks looking for hunt related physical training... I recommend you take a look at these guys:
they have some serious, world class athletes putting together their programs (professional strongmen, military SOF officers, etc).. all of them are extremely experienced hunters (across a wide variety of hunting situations..)... and... you're supporting a US military veterans organization as well (the owner/founder is currently serving in eastern Europe as an officer in the 4th ID)... he also happens to be the son of a very good friend of mine (in the interest of full disclosure))...
they also have some pretty nice (and well made) logo'd materials.. hats, shirts, hoodies, etc..
their podcast is well done and they have some interesting guests... and their social media is worth looking at if you're into that sort of thing as well...
