answer:Try a spin/rpm class at a nearby gym, they’re really helping me get fitter. But with your runs, set a time limit, run the same track a couple of times each week, but try and get a little bit further distance each time. Just a bit- because if you’re turning around and coming back the same way that distance is doubled, and a little bit more each jog in the same amount of time will really help. So say for example you decide you’ll run for 20 minutes. Run for 10 minutes nice and steady, just seeing how you go, then turn around and run back (you should actually be quicker on the way back because you know you’re on the home stretch). Remember where you got to. Next time, run for 10 minutes again but aim to get say 100m further along the track, turn around and come back.
