Is 76kg too much on a suspended floor/ not solid floor plus 120kg wife! 
I have a treadmill (ketler arena folding) that weighs 76kg and am concerned that it may be..... 
The specs do not specify solid floors only

I'm not a structural engineer but I bet most wardrobes and large beds far exceed 76kg

I'm sure it will be fine as long as it's not in a loft that doesn't have proper specced joists. Many houses will have a bath supported by a timber subfloor. We had a cast iron bath that would have weighed over 250kg when filled which was never an issue.

Thanks thats reassuring

its on the groundfloor but the boards appear slightly "FLEXIBLE"

I was expecting it to weigh 200kg + - I tried to move it and ended up sitting up againt the wall pushing with my feet and even then, I struggled

it appears to have a huge block of concrete in the base (stability ?)

Remember when people often had pianos in the house.

If its a folding one then they normally have wheels on one side of the upright assembly so you raise the treadmill bit up & then tilt the upright bit onto the wheels & then you can wheel it about

I think a floor in a UK house or flat that's been designed to modern standards ought to be adequate for a 200 kg point load placed anywhere on it.

The design standard BS EN 1991-1-1 specifies that floors in areas for residential use should be designed to resist an imposed load of not less than 2kN, usually assumed to act on a square area of side 50mm (concentrating the load on a smaller area is worse, so spreading it out over the area of the treadmill will only help).  

2kN is approximately equal to the weight of an object of mass - you guessed it - 200kg.

Its a kettler arena !

My treadmill (different make but very similar) is in an upstairs bedroom on a suspended timber floor. There are no structural safety issues. However when you are pounding on a treadmill on a suspended floor it is much,much noisier than on a solid floor such as a garage.
Not a problem for you on the ground floor but for this reason treadmills are usually prohibited in flats. Everyone knows when you are going for a burn!

If its flexible it maybe a floating floor
