Boxing is an individual sport. A coach will never bench you, but if you don’t work hard and fight at your best, you may still find yourself on your seat.
Train your weaknesses. It’s everyone’s natural tendency to gravitate towards what comes naturally, what they like the most and what they excel at. Focus on your weaknesses. It may be harder and a little more unpleasant, but if you don’t pay attention to what you’re lacking…someone else might.
