Rip,
Good video sir, and one I was amazed to see. I'm glad you explained that the purpose/necessity was for building strength for your Bench and it served as an assist for Intermediate programming. One thing I did very much enjoy and find funny, was your very detailed explanation of the Bench you were using, including height, length, etc. I chuckled at this and can only imagine you stated that so people don't ask a stupid question like "what can I do this exercise on?" I am honestly waiting for people to ask if they can use a non-standard Bench, you know someone will.
How do you feel this exercise compares to say a Close-Grip Bench Press for improving Tricep strength and development? I know a lot of Intermediate programs suggest the Close-Grip, but avoid exercises such as the skull-crusher, etc. for obvious reasons.
Also wanted to ask. When I was a wee lad starting out lifting, my father had me do an exercise known as the Chest Expansion, where you lie prone and place your upper back perpendicular to the length of the Bench (so you minimize the amount of your body actually supported by the Bench and support the bulk of your weight with your supporting legs) and perform a similar movement as this exercise. It supposedly would broaden your chest, etc. Is this a bro/bodybuilding version or just something you've never heard of and is crazy? It seems that it would work similarly although adding a perhaps unnecessary difficulty by supporting the body without the aid of the Bench.
Thanks.
