Sunny Health and Fitness Treadmill Key Features
Drive –
The Sunny Health and Fitness SF-T4400 Folding Treadmill has a 2.20 Peak HP drive system.
It is a motorized model, so it needs to be plugged into an electrical outlet. The power cord is 6′ long. It connects via the treadmill’s front base.
Construction & Finish –
The treadmill’s alloy steel frame is powder-coated to resist scratches, chips, and corrosion.
The arm joins, motor casing, dash, and feet are toughened plastic.
Smoothness, Stability, & Noise level –
The belt is cushioned to reduce joint impact, making for smoother, more comfortable sessions. Shock absorbers further enhance workouts and reduce leg fatigue so you can work out for longer.
A solid frame provides stability, as do non-marking feet in the base. The feet adjust, enabling you to work out even if your floor is slightly uneven.
There’s no notable movement during workouts that can occur with foldable treadmills in this one’s price bracket.
As with any treadmill, the noise level increases when you put in more effort. However, this model is quieter than some others. You will be able to hear the TV when working out, and your workouts should not disturb anyone else in your household.
Speed & Incline –
Speed options range from 0.5 MPH to 9 MPH. 
Press the up or down arrow to change the speed in 0.5 MPH increments, or press one of three Quick speed options to go to 2, 4, or 6 MPH immediately.
The controls are in the right-side handrail, along with a Stop/Start and a Pause button.
The treadmill can be used flat or on one of the two incline levels, these being 2 degrees and 4.37 degrees.
While not extreme, adjusting the incline will enable you to vary your workouts and make them slightly more challenging.
To adjust the incline level, remove the fixing pins from each side of the frame, move the frame to the desired slant, and reinsert the pins in the relevant hole.
You will need to adjust both sides, one at a time.
Programs –
9 pre-set interval-focused programs target various fitness aspects, including speed, time, distance, weight loss, etc. Speed changes for these are automatic, but you can adjust the speed, length of the workout, etc., at any time.
A manual program lets you create customized programs, with adjustments possible on the fly.
The programs are activated by pressing a button on the console.
Pulse rate sensor –
The treadmill’s cushioned handlebars house a pulse rate sensor that will enable you to work in your ideal heart rate zone to get the best results.
LCD screen –
The Sunny Health & Fitness SF-T4400 Motorized Treadmill has an easy-to-read, backlit LCD monitor that shows Time, Speed, Distance, and Calories. It also displays your pulse count when gripping both pulse sensors in the handlebars.
Time is the elapsed time of the session in minutes and seconds.
Speed is your current workout speed in miles per hour.
Distance is how far you’ve covered in miles.
The Calories reading is the number of calories you’ve burned during the session.
Pulse is your current pulse reading from 50–200 BPM.
There is also the facility to determine your Body Mass Index.
To do this, enter your Gender, Age, Height, and Weight, press the two keys stipulated in the user manual, grip the pulse sensors for 3 seconds, and your BMI will appear on the screen.
Access to the above metrics makes tracking your progress and setting new fitness goals easy.
To begin your session, insert the magnetic end of the safety key into the slot in the dash, then press start. The belt will start moving at 0.5 MPH.
The treadmill will enter Power Saving mode when 10 minutes of inactivity is detected.
Alternatively, press the Off button or remove the power cord from the electrical outlet.
Folding/Unfolding –
You can lift the treadmill’s deck to save space when it’s not in use; however, it won’t fold flat enough to fit into a closet or under a bed.
To fold the deck, push upwards on the mainframe with one hand until you hear a click indicating it is locked into position.
To unfold the deck, support it with one hand, then push lightly on the air pressure cylinder with one foot as you press down on the frame.
The treadmill’s Soft Drop system will take care of the rest, slowly and smoothly dropping the deck so you won’t have to worry about it damaging your floor.
Transport wheels –
Built-in transport wheels enable easy relocation of the treadmill when required by tipping and rolling it.
Accessories –
A conveniently located ledge in the dashboard’s center will hold a smartphone, Kindle, or tablet, enabling you to access your favorite electronic device during workouts.
A water bottle and a cup holder – one on each side of the dash – enable easy access to a refreshing drink.
The following two sections of this Sunny Health and Fitness SF-T4400 Treadmill review cover its pros and cons.
Assembly –
The Sunny Health and Fitness SF-T4400 Treadmill comes partially assembled. Completing the job should take around 20 to 30 minutes. The directions for doing this are easy to understand and execute, and the needed tools are supplied.
In a nutshell, you will have to insert the two uprights into the base and secure them, attach their covers and the dash, and connect the console’s wires.
