The NCSF Personal Trainer App provides immediate information to optimize your training experience. Easily calculate the resistance for your client’s next set, determine the percentage of effort per exercise, or identify the nutritional needs of your client following an exercise bout based on caloric expenditure. The Personal Trainer App provides essential information to maximize the time-effort relationship, create more effective programs, adjust intensities, and determine physiological metrics to demonstrate results. Put the science into your workouts without lengthy, long-hand calculations or textbooks. Evidence-based, peer-reviewed data meets technology, allowing you to simply plug and program. The Personal Trainer App will allow you to track physical performance, provide clients with instant feedback, and complete 14 different calculations in any fitness setting.

The NCSF Personal Trainer Calculator includes:

1 Rep Max – accurately predicts 1RM safely and effectively for any exercise

Multi-Repetition – accurately predicts the appropriate weight for a given number of repetitions based on 1RM

Percentage of Max Effort – estimates how hard a set of resistance training will be relative to max effort; great for programming progressions

Daily Energy Nutrient Intake – provides you with evidence-based nutrition recommendations for carbohydrate, protein, and fat in grams and calories per day based on physical activity level and cardiovascular risk

Caloric Expenditure – quickly determines calories expended from physical activity based on human research

Target Body Weight – accurately assesses weight loss adjustments based on current and goal body fat

Resting Metabolic Rate (Harris-Benedict) – estimates the number of calories expended per day based on gender, age, height, and weight

Resting Metabolic Rate (Lean Mass) – estimates the number of calories expended per day based on lean mass

Body Fat – rapidly provides body fat percentage from 3 site assessments

Body Mass Index (BMI) – identifies predicted risk for disease and compares with healthy values

Target Heart Rate – quickly identifies ideal heart rate training zones for effective aerobic training

Max HR Calculators – Determining Heart Rate Max is necessary to accurately identify an exerciser’s relative training zones for improved cardiorespiratory fitness or for competitive event preparation.

VO2max - Volume of Oxygen – Easily calculate your VO2max using the Astrand treadmill protocol, 1.5 mile run test or one-mile walk test and compare your aerobic capacity to the population norms.

Exercise Energy Expenditure - This calculator will predict caloric expenditure based on the intensity and duration of exercise coupled with the individual's current cardiovascular fitness level.

Stumbled across this by accident. Nice. I was a member it cannot afford to renew. Requires a membership number. My membership expired donut worked for 20 minutes. Oh well.

Doesn’t work for Online Learning

I thought I would be able to access the online learning textbook and video’s via this app but I cannot, which may be my own fault for not reading the description well enough but that seems like a no brainer to have on here. Beside that the overall app is out dated and glitchy. It won’t let me select stuff and its resolution needs to be updated. I downloaded this app 5 minutes ago and I am ready to delete it. I would happily download again and re-review if they update it.
