Rides for overweight unfit people?

I think tester and dmczone need to realise that interval training is an advanced fitness technique, not something for the unfit and seriously overweight. Disadvantages of HIT for such people include

• Much higher likelihood of injury (completely frustrating the fitness/weight-loss goals).
  
• Is much tougher and likely to discourage the unfit.
  
• Intense activity stimulates hunger cravings, which requires discipline to manage. The unfit and fat are much more likely to binge after this than after moderate activity.
  
  
  
  

Really, get a sense of proportion.
