"People keep asking me what I'm on. I just tell them I'm using MuscleCALC. I've gone from 160 pounds to 200 pounds of muscle in a year."

— R. Aquino

Most people don't build strength and muscle as fast as they would like because they don't have a plan, based on a record of past performance. They don't write things down or they have no way to ensure over an extended period of time they are lifting the correct amounts of weight to stimulate muscular growth to occur. Over time, they cannot remember what their body has remembered.

With MuscleCALC, you won't ever guess what weights you need to choose for every exercise you perform. It remembers.


The MuscleCALC system uses a simple 3 step procedure for recording your workout and providing an analysis tool for you to build strength and muscularity:

STEP 1: Use the printed Daily Workout Journal to record your workout.

Using the LiftScript™ notation system, record your workout in detail with minimal writing. It's quick and easy.

STEP 2: Record your best efforts in the MuscleCALC Spreadsheet.

Record your best weightlifting efforts, based on the notations in your Daily Workout Journal pages.

STEP 3: Plan your workouts, based on the MuscleCALC Spreadsheet.

Review and print out the MuscleCALC spreadsheet and analyze what you need to do for your next training cycle. (Fold it up, stick it in your gym bag and take it with you to the gym—it's your map to strength and muscularity.)

Sound simple? It is. It works.

Track Your Weightlifting Progess

The Summary feature automatically tracks your weightlifting progress over time or across lifting cycles.

Track Your Strength

Use the One Rep Max (1RM) Calculator to help you determine the proper weights you should be using in your workout, in order to improve muscular endurance, size, or strength. If the numbers are going up over time, then you are getting stronger. You can try the 1 Rep Max Estimator live on our website to see how our spreadsheet functions.

Using this simple, 3 step procedure, you'll never workout the same again. You'll start thinking about surpassing personal bests with every set you perform (after warmups, of course). It becomes addictive.

The MuscleCALC system will change your body. This system has been used for over two decades with 100% success. Every person who has used MuscleCALC has attained their most muscular level of conditioning after at least 3 months of consistent, dedicated use (given an appropriate diet and rest).

MuscleCALC focuses your entire workout around the central tenet of weightlifting--Progressive Resistance. Except now it has you focusing on maximal exertion of both fast-twitch (Type I) and slow-twitch (Type II) muscle fibers, since you will be attempting to set personal bests across the entire range of repetitions, from low (3-5 reps) and moderate (8-12), to high (15-100).




MuscleCALC is not for electronically recording each of your workouts (that's done on the included paper form) or for creating workouts (that's what Exercise Genie does). Electronically recording each workout is just too time consuming and not worth the effort. The MuscleCALC system, consisting of the paper-based Daily Workout Journal form and the MuscleCALC Spreadsheet puts most of your effort in the gym—not in front of the computer.


When you purchase and download MuscleCALC you instantly receive the following files:

Packaged in spreadsheet format, MuscleCALC is compatible with Microsoft Excel.
