Store the concrete powder mix in a heated garage or other warm area until use and mix it with hot water when you are ready. Allow the concrete to stiffen after it has been poured and then cover it with insulated blankets to keep it warm or keep the tent up and the space heater running overnight.
A plankowner (also referred to a plank owner and sometimes a plank holder) is an individual who was a member of the crew of a United States Navy ship or United States Coast Guard cutter when that ship was placed in commission. Originally, this term applied only to crew members that were present at the ship's first commissioning.
The concept of a plank is pretty simple: You hold yourself up in a pushup position for a set period of time to tone your core, glutes, and hamstrings. But while you probably already know how to do a plank, you might be hazy on how long you should actually hold one to max out results. The answer is not as simple as you think. Albert Matheny, R.D., C.S.C.S., co-founder of SoHo Strength Lab and advisor to Promix Nutrition, says you can plank daily, but the length of time you should hold a plank for can vary from 10 seconds to a minute.
