The Best Fold Flat Underbed Treadmills

You want to get a great cardio workout at home but you’ve got extremely limited workout space in your home or apartment. What you need is a foldable treadmill that you can pack up and slip under your bed when your workout is over. When you’re shopping for an under bed foldable treadmill, however, you have to be a discerning buyer – many of the products on the market can best be described as cheap and nasty.

In this article, I’ve gone deep into the under bed foldable market to sort out the best from the rest. Here are the 10 best fold flat under bed treadmills on the 2021 market.

The 10 Best Fold Flat Treadmills: 

1. XTERRA Fitness TR150 Folding Treadmill

XTERRA Fitness TR150 Folding Treadmill
  • 3 level manual incline
  • 12 programs
  • Max user weight 250 lbs

The Xterra Fitness TR150 folding treadmill is one of the most robust foldable treadmills that you can buy for under $300. It is powered by a 2.25 HP motor that provides a maximum speed of 10 miles per hour. The non-slip rubber running belt is 16 inches wide and 50 inches long. The XtraSoft cushioning system provides three shock-absorbing layers to ensure joint friendliness. 

This treadmill features a 3 level manual incline function. Adjustable rear stabilizers allow you to get the ideal positioning of the running bed. The console features an attractive LCD display that provides a readout of your training time, distance, speed, and calories burned. It also monitors your pulse rate thanks to pulse sensors embedded into the handrails. There are 12 pre-set programs built into the console, each of which provides you with a 30-minute workout. 

There is no Bluetooth functionality on this treadmill. 

2. GoPlus Folding Treadmill

GoPlus Folding Treadmill
  • Foldable
  • 2.25 HP Motor
  • Max user weight 265 lbs

The GoPlus folding treadmill is a walking pad treadmill that stands out due to its superior running belt cushioning. There are 5 layers of padding to make this the most joint-friendly budget under bed treadmill that I’ve come across. 

The handrails that come with the GoPlus Folding treadmill are detachable, making this an amazingly compact unit. The console is built into the base of the treadmill and provides a running readout of all of your key training data. The console also features Bluetooth speakers. The treadmill provides both walking and running modes, with a max running speed of 7.5 miles per hour. The deck size of the Go Plus Folding treadmill is 40 inches x 16 and it has an impressive max user weight of 265 lbs thanks to its sturdy frame construction. 

3. Lifespan TR200 Compact Treadmill

Lifespan TR200 Compact Treadmill
  • Compression shock system
  • Max user weight 350 lbs
  • 2.25 HP Motor

The Lifespan Compact Treadmill is an under bed or under desk walking treadmill that has no side rails. This is an amazingly solid and robust treadmill with a max user weight of 350 lbs. That’s considerably more than the GoPlus. However, the max speed on this machine is 4.0 miles per hour, which limits you to fast walking. You can adjust the speed from 0 to 4 mph with a simple touch of a button. 

The running belt on the Lifespan Compact Treadmill measures 50 x 20 inches, which is pretty generous for an under bed treadmill. It features a handheld remote control style console that allows you to adjust the speed while also providing feedback on your training diagnostics. There are six compression shocks built into the Lifespan Compact Treadmill that deliver a joint-friendly workout experience. 

4. InMovement Unsit Under Desk Treadmill

InMovement Unsit Under Desk Treadmill
  • Very compact
  • Wide walking belt
  • Max weight 400 lbs

The InMovement Unsit Under Desk treadmill is a uniquely designed walking treadmill that is not as long as most conventional alternatives. Rather than a rectangular walking surface, this one is much closer to square, with a 30-inch width and a 40-inch length. That allows you to achieve a much freer lateral walking gait. 

The InMovement only allows for a max speed of 2 miles per hour which is a gentle walking pace for most people. The maximum weight is an impressive 400 pounds, making this a very good option for overweight or obese people who are wanting to ease in regular exercise. The machine operates extremely quietly, which makes it ideal for an office environment. If you’re wanting to consistently burn calories while gently walking as you are working, then this is a good option.

The InMovement Unsit Under Desk Treadmill allows you to access your training data right on your phone via the Unsit app. The cushioning on this treadmill is supportive enough to ensure joint integrity but too much to interfere with your natural walking motion. 

The InMovement Unsit Under Desk Treadmill is one of the most expensive under desk or bed treadmills that you will come across, with a price tag of around $2000. It comes with a lifetime frame warranty, with 3 years on parts and one year on labor.

The running belt on the Murtisol 2 in 1 folding treadmill offers a generous level of joint protection thanks to the 5 layer non-slip running belt.

What to look for when buying a fold flat under bed treadmill

Once you have decided to invest in a fold-flat under bed treadmill, here are several factors to take into account when making your selection:

Stability 

The biggest problem with many of the under bed foldable treadmills on the market is that they are not sturdy enough. When a treadmill frame is made to be foldable, it necessarily gets weaker.

The stability of a treadmill, however, is key to getting a consistently safe and comfortable workout. The maximum user weight limit of the machine is a good indication of the stability and strength of the frame. Look for an under bed foldable that has a max user weight of 250 lbs or above.

Horse Power

The Horse Power of the motor will determine how fast you can walk or run on it and how smoothly the running belt will operate. Decide if you want to use the treadmill for walking, jogging, or running. For walking workouts, you can get away with a motor that has a 15 horsepower rating. To be able to jog you’ll need to step it up to 2.5 HP. However, to run at a higher speed you will want to find a treadmill with at least a 3.0 HP motor rating.

Running Bed Dimensions

The dimensions of the running bed are vital to proper performance. If it is too small you are going to be too constricted to achieve your natural running gait. If the running bed is 16 inches by 40inches or smaller, you will struggle to have enough room to move naturally. Ideally, the bed width should be 18 inches or higher with the length being greater than 45 inches.

Console

You will not get a high spec console with a foldable under bed treadmill. However, you should expect it to provide you with a running readout of your time, distance, speed, and calories. 

Warranty

Even though an under bed foldable treadmill is less expensive than many alternatives, you should still expect a good level of protection by way of the warranty. A good warranty for a foldable is 5 years on the frame, 2 years on the parts, and 12 months for labor.

FAQs

Is a treadmill a good way to lose weight?

Yes, a treadmill is a good way to lose weight. However, to get the most out of your time on the treadmill, you need to be moving at a decent speed. The best form of treadmill workout for fat loss is high-intensity interval training (HIIT).

Is a treadmill bad for your knees?

Running on a treadmill may cause problems for a person’s knees. Many people run on their toes on a treadmill which increases the amount of knee bend. As a result, it absorbs more force with every footstrike. 

How often should you work out on a treadmill?

If you are working out on the treadmill to lose weight, you can exercise every day on the treadmill. Your sessions should be between 2-40 minutes. If you are training for cardiovascular benefits, you should work out on the treadmill 3-4 times per week.
