- Be as honest as possible. Don’t count half reps or reps done with poor form. You’ll only be kidding yourself.
- Make sure your training conditions are the same. If you’re feeling ill, or need to rush the workout in less time, these are different circumstances that are not comparable to your normal workout. Keep a note of this.
- Review it prior each workout. Use it as a written motivator. This is how I use it and why I rarely use pre workout products. To me, nothing fires me up in the gym more than the prospect of beating my previous performance.
