 Unmotivated clients with the same excuses.
 Irregular income.
 Pressure to sell gym memberships and meeting sales quotas.
 Clients wanting a magic pill not sound nutritional advice.
 Waking up early and getting home late.
 Missed weekends with family.
 Gossip partner, not trainer.
 Sexual harassment.
