This heart health concern has me puzzled. If one put on a 40 lbs backpack and went for a 3 hour hike would one need worry about putting too much stress on the heart? If not, why would one worry about the scenario described in the OP?[/quote]
My thoughts that made me decide not to do this myself was that I would be wearing a 40lb vest all day, every day. My thoughts were, and I could easily be wrong, that all that I would really be doing is making my heart work harder for 9-13 hours a day. When I would normally be at a normal heart rate and blood pressure level.
HIIT training, cycling, walking, hiking all these forms of “exercise” are great and have their place and can be used to enhance a persons well being. Wearing a 40lb vest at your stand-up desk for 9-13 hours a day is just an unnecessary strain on your heart for little to no reward. IMO
“About a month ago I started wearing a 40 lb weight vest for about 3-4 hours in the morning.”[/quote]
I probably should have been more clear. My thoughts and comments were based on my plans of wearing one all day.
I still would not recommend wearing a weight vest at your stand up desk 3-4 hours a day. Instead I would recommend wearing a weight vest every day you go on a long walk, do plyometrics, do sprint work(really I would suggest a small parachute here, or if you have a workout partner have them attached to you with a bungee cord rope), etc. I don’t know man, I just don’t like the idea of wearing one when you’re not working out.
