The main thing that comes out of this video is that The Rock has a commanding physical presence. Well that's obvious. He is 6 foot 5 (1.96m) and 260lbs (118kgs).
From the video we are shown that he uses he physical presence in not an intimidating way but in a very engaging way. He uses big hand gestures and he also had a booming laugh which although he is this giant he comes across as very approachable and someone that you can admire.
For those of you that don't know me I'm 6 foot 1 (187cm) and 210lbs (95kgs). So I'm no runt of the litter.
I've been told a few times in my life that I should use my size as an advantage. It is just in the last few months that I have finally realised what they mean by that. I was told at my gym that when I left I should really pull my shoulders back. I have integrated that in my lifting but I also have integrated it in my everyday life. So now I have pulled my shoulders back, sucked in my gut and I feel a million times better. I feel a lot more confident as I am not hunched over and I am looking ahead.
I believe for taller, bigger people that you should use your size, not for intimidation but that natural presence that will have people listening to you but do it in a friendly way like The Rock. This way you will win respect from the people around you and undoubtedly win a whole bunch of friends as well.
