Leg press, deadlifts, RDLs, lunges, leg extensions, leg curls, hack squats, split squats. All those will hit your legs, plus there variations. Do some sprints, run hills, stairs, those will hit your legs. Im sure there are more lifts I can't think of this second as well.
While natural gas occurs in nature as a mixture of methane and other gases, propane is actually a byproduct of both petroleum refining and natural gas processing.
If you put propane to a natural gas appliance or bbq, you would have one heck of a huge fire, and it would be extremely dangerouse. As for the answer two down from mine, that is incorrect. Natrual gas is lighter than air, propane is heavier. bought a weber grill that is set up for natural gas and I need it to work using propane. I wanted to just take off the natural gas hose and attach a propane hose and regulator, but weber said I couldn&#39;t do that.
