Have you tried one of Tongham’s excellent outdoor facilities yet?  There is an outdoor gym with a selection of machines for use by adults and young adults.  It is found at the top end of the recreation ground.  The machines cover various activities including rowing, cross walker, stepper and for upper and lower body strength.   Instructions are available on them (quite small) with copies on the noticeboard and below here.  

All equipment is used at the user’s risk.
