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.
Also, natural gas burns much cleaner than propane. So natural gas is better for the environment and you don't get as much exhaust from the burning propane which can end up on your food and float around your party. Lastly, natural gas, connected to your house won't run out until the gas company does in 30 to 40 years.or many of these the difference is just a few parts. As I said, natural gas has about half the BTUs (amount of heat generated) as propane. Simply plugging in a natural gas line to your propane grill won't work, even if you could get the connector.
