treadmill, solution of two situations are as following:

1.2 Running Belt tension
When you plant your foot on the belt, if you can feel a slipping
sensation then the belt has been stretched and is slipping across the
rollers, which is a normal and common adjustment is needed on a new
treadmill or using for period of time. Tension both the Allen bolts of
rear roller 1/4 TURN as below figure to eliminate this slipping. Try the
treadmill again to check for slipping. Repeat if necessary, but NEVER
TURN the roller bolts more than 1/4 turn at one times.
