The world number two is currently training hard for next month's World Championship with her coach Vimal Kumar at Bangalore's Prakash Padukone Badminton Academy.
The 25-year-old's daily training regime consist of four hours on the badminton court and another four hours in the gym, as she attempts to improve both the quality of her play and her fitness.
"My performance must be the best as per my analysis. Further it depends upon the overall body health of mine," Nehwal said.
"As a badminton player of India, I play almost all the tournaments slated for the year 2015-16. For example, World Cup, Japan Open, China Open, Denmark Open, France and Hong Kong open by the end of 2015.
"My training part is very good, I am getting all possible help and facilities required for the improvement of badminton player game and skill."
Nehwal became the first Indian shuttler to be ranked No 1 when she reached the top spot in the rankings in April this year, but has since lost that honour to long-time rival Carolina Marin of Spain.
"The number one is not static, it changes with the time and performance. Chinese girl Li Xuerui who was number one for almost entire year has slumped to third position," she added.
