A pocket PC/desktop computer/PDA weight-training system designed to instantly calculate the domains of strength, power, weight-training endurance, work, aerobics, and body fat percentage. The system calculates the difference and percentage of change of each domain from weight-training session to session, reflecting a complete evaluation of overload.

The system also calculates the percentages of the user's 1-RM. When a weightlifting scheme grows ineffective, the user can choose another weight scheme related to their 1-RM, or they can change the exercises using a drop-down menu of complete exercises for each body part. The system also calculates the total rest days and days between trained body parts to help the user evaluate his/her optimal recuperation cycle. Lastly, the log calculates the user's maximum heart rate (male and female) and gives ranges from 25 to 100% for optimal aerobic training.

The nutrition component calculates 47 nutrients (including amino acids), as the user marks servings of consumed foods. The user sets consumption goals, and the system reflects the difference of the goal and what was consumed. The aerobic/activity component gives the user a 30-day horizon analysis of muscle/fat gain or loss, based on the user's marked activity, calorie intake and the calculated basal metabolic rate.
