Over 15k steps
Only with tennis.
One hours of service practice at the empty court.
Several sets of doubles tennis play.
Considering the steps count
Maybe 5 sets of doubles sets.
Getting accustomed to tennis shits
With about two weeks of play
After about one years of no tennis and nearly no physical activities.
Playing tennis is really good for vivid life.
Good sports and good dapp.
May sports and actifit live long.
