This treadmill is used under the standing desk at work, home, or school so that you can work and walk.LifeSpan TR1200-DT3 Under Desk Treadmill Review

It is not healthy to just sit on a chair all day long, 24/7 in a loop. You can always get under desk treadmill such as the LifeSpan TR1200-DT3 to help you walk while you work.

But before we go into the full review of this unit there are concerns and questions many people have, including you maybe, about the possibility of being able to walk and work at the same time. Some individuals can’t just wrap their heads around that idea and thus, they are not sure if they should or should not get one of the under-desk treadmills.

We can understand these concerns because it is unusual to walk on a treadmill while you work on your computer and having to deal with mouse precision and all that.

This is what we are going to address as best as we can so that you can get rid of that skepticism and regain your confidence and do the right thing.

Can you type on a computer while you walk at the same time?

Yes, you can, many people, including those that were once a skeptic, are using the LifeSpan TR1200-DT3 Under Desk Treadmill to walk and type on their computers.

This is possible because while you are walking, your hands are not. They are rested in front of the keyboard and so you should be able to type just as you could when you are not walking.

Can I have total control of the mouse?

This is yet another aspect that is a little bit different from typing because in some cases you may be required to be précised with the mouse control and so you will not need any sort of distraction.

But again, you can have some level of control over the mouse, but in case you need the precision most designers or video game players need then you might want to reduce your walking speed.

Walking at 0.5 mph should be ideal for having that extreme precision when working with a mouse, any speed that is more than that may cause you to have a hard time trying to use the mouse for precision purposes.

How about my energy and concentration while working and walking?

We get it, the belief is that one might get distracted by the walking, hence lose concentration on what he/she is doingLifeSpan TR1200-DT3 Under Desk Treadmill Review on the computer. And some people also think that you burn a lot more energy while walking and therefore lose the energy that may be required for the work.

On the contrary, if you are going to be walking for 3 to 6 hours in a day is not too much to drain your energy and besides you won’t be doing that at a stretch. And as for concentration, you tend to be more alert while walking than when you are sitting. The body is working and as a result, there is adequate blood circulation that gets to the brain and refreshes your concentration.

One user says ‘’it’s amazing how much more alert I feel now than when I used to just sit down all day programming’’.
