Dear BodyWeightCulturirst,
We would like to apologize to all of you for any inconveniences caused while our site was down for a few hours yesterday. We were having some server problems, but now everything is back to normal.
Also we have put together a four minutes challenge. In four minutes you will challenge your core strength, cardiovascular endurance, total body muscular endurance and will power. All this without getting up from the pushup position.
Please try it and let us know how far you have made it. If you can complete the challenge, please make a video and we will proudly put it up for everyone’s motivation.
P.S. If you are in the military don't show it to your drill sergeant, you may regret it later.
Your friends at bodyweightculture.
