You should know how many gallons of fuel your airplane holds, but how much does it weigh? Avgas weighs 6 pounds per gallon, so multiply the gallons by 6. (If your airplane burns Jet-A, you’ll have a table that will tell you how much it weighs at various temperatures—it’s usually...
If you increase how much you Deadlift with a neutral spine, then your back got stronger – whether you got sore or not. Otherwise you couldn’t lift the weight with a neutral spine. Soreness usually happens if you do something new. If you suddenly do five sets instead of one. Or if ...
