Not all treadmills are created equally, some can support larger weights than others due to specialised welding and heavy duty equipment & mechanical elements being implemented (which in turn does tend to make them more expensive than your standard treadmill). This treadmill guide takes a look at the best treadmills for each specific user weight capacity range -- specifically for the following categories: over 250 pounds, over 300 pounds, for up to 350 pounds, 400 pounds and the max of up to 500 pounds.

So you can be assured that the i) the treadmill will be more than sufficient in supporting your weight and ii) you are getting a top quality treadmill (which has been selected on how well it provides you with a cardiovascular workout, the practicalities & features along with it -- and general 'bang for buck') .

The F80 Folding Treadmill (2013 Model) By Sole Fitness

Weight User Capacity: up to 375 pounds. Dimensions: 35 x 58 x 80 inches. Rating: 82%.

No one makes exercise equipment quite like Sole Fitness -- their machines are built like tanks and are made to endure heavy impact exercise on a continuous basis, this F80 is certainly testament to that (e.g. the precision welded frame, rollers, high torque motor w/ flywheels). The running deck is fitted with cushion flex whisper deck that ensures the treadmill is practically silent whilst you're running as well as protecting your joints by up to 40% (when compared with running on asphalt). It is also installed with a SOLE LCD display to offer clear readings of running info (speed, distance, calories burned etc.) in conjunction with an integrated message board. Despite, it being such a large treadmill and machine -- it is space conscious given the fact (like the other treadmills above) it can fold up with an easy assist mechanism.

Best Treadmill for 500 lbs

The L980 Club Cardio Trainer Treadmill By Landice

Weight User Capacity: up to 500 pounds.

There aren't many treadmills out there that can cater for an individual weighing more than 400 lbs and the ones that do are pretty expensive like the highly rated L980. This being said, you are getting a treadmill that is at the very cutting edge of fitness engineering and technology with 'uncompromised materials' (e.g. the exact material used in luxury aircrafts) -- put simply it really doesn't get any better than this -- this is what the pros use. For instance, the treadmill decks used with Landice are 33% stronger than the next best competitor and the latest medical research has produced the VFX shock absorption proving to be pretty much the best at reducing impact on your knees (and other joints). An incredible treadmill, but very expensive. Yet again, aren't you and your health worth it?

Also, if you have any queries, concerns or general remarks regarding either the overview of the best treadmills for 250 pounds, 300 pounds, 350 pounds, 400 pounds and 500 pounds or about any of the treadmills specifically featured above (e.g. the specific workout programs of the LifeSpan TR1200i and how it compares to the TR3000i etc.) then please do not hesitate to make them in the comments section that you will find just below and we will be sure to get back to you as soon as possible.
