Well, i'm having the same problem as you at the moment, but here's an exercise schedule.
1. Jog for 30 mins (jogging in place doesnt count!)
2.Stretch, touch your toes, do the flamingo, anything that stretches out leg muscles.
3. Work hard. just because you arent working on your legs doesnt mean its not working at all! Do countdowns (jog, 10 push ups, 10 sit ups, jumping jacks, jog, 9 pushups, 9 situps etc.)
4. After, walk for 5 minutes.
i hope it helps!
