Pedals come in two thread sizes, 1/2"-20tpi and 9/16"-20tpi with the left side pedal being left-hand threaded in both cases. The 1/2" threads are usually used on one-piece cranks on department store quality bikes while 9/16" threads are used on better quality road and MTBs.
Try a set of 9/16" pedals and see if they fit. Any bike dealer will have them.

Is this a new or used bike? If you are using 9/16 pedals installed properly, then it is possible that the cranks have become worn or damaged before you got it.
There is also a third, obsolete pedal thread, 14 mm x 1.25 mm thread. There aren't a lot of them around, but they are very close to the 9/16 thread, but slightly undersized. You might run into them with a random very vintage spare parts selection.
Anyway, make sure you are using good "new" pedals.
Some exercise bikes use proprietary parts that are hard to source. I'm doubting they would use non-standard pedals, but you may need to replace a crankset, or it is possible to helicoil damaged pedal threads if necessary.

There is a fourth pedal/crank arm attachment but I doubt it's what the OP has. Some very small kids bikes have had the pedal spindle slid through the unthreaded crank arm and a retaining nut spun on the spindle behind the arm.
The first and easy possibility is mixing up 1/2" and 9/16" pedal threadings. Andy
