Formulas Used

Total Workout Time

Total Workout Time = Warmup + (Work Interval + Rest Interval) × Rounds + Cooldown

This formula calculates the total duration of a workout session. It sums the warm-up time, the combined work and rest intervals multiplied by the number of rounds, and the cool-down time. It provides a comprehensive estimate of the time required for the entire workout, encompassing all phases of the session.

Estimated Calories Burned

Estimated Calories Burned = (Work Time × 0.15) + (Rest Time × 0.05) + (Warmup/Cooldown Time × 0.08) calories per second

This formula estimates the calories burned during a workout by assigning different calorie burn rates to work, rest, and warm-up/cool-down periods. Work time is multiplied by 0.15 calories per second, rest time by 0.05 calories per second, and warm-up/cool-down time by 0.08 calories per second, summing to the total energy expenditure.

Work-to-Rest Ratio

Work-to-Rest Ratio = Work Interval ÷ Rest Interval

This formula calculates the ratio of work interval duration to rest interval duration in a workout. It divides the time spent on active exercise by the time spent resting within a round, providing a metric to assess the intensity and balance of the workout. A higher ratio indicates a more work-intensive session.

Variables Explained

Warmup

The duration of preparatory activities before the main workout, typically 5-15 minutes of low-intensity exercise to prevent injury and enhance performance.

Work Interval

The duration of active exercise periods within each round, typically measured in seconds, representing the high-intensity effort in a workout.

Rest Interval

The duration of recovery periods between work intervals within each round, typically measured in seconds, allowing the body to recover before the next effort.

Rounds

The number of times the work and rest cycle is repeated during the workout, represented as a positive integer, determining the workout’s endurance component.

Cooldown

The duration of low-intensity activities after the main workout, typically 5-10 minutes, to promote recovery and reduce muscle stiffness.

Total Workout Time

The complete duration of the workout session, encompassing warm-up, work, rest, and cool-down periods, typically measured in minutes.

Work Time

The cumulative time spent on active exercise across all rounds, typically measured in seconds, used in the calories burned calculation.

Rest Time

The cumulative time spent on recovery periods across all rounds, typically measured in seconds, used in the calories burned calculation.

Warmup/Cooldown Time

The combined duration of warm-up and cool-down periods, typically measured in seconds, used in the calories burned calculation with a specific calorie burn rate.

Estimated Calories Burned

The estimated total energy expenditure during the workout, measured in calories, based on the time and intensity of work, rest, and warm-up/cool-down periods.

Work-to-Rest Ratio

A dimensionless value representing the ratio of work interval duration to rest interval duration, indicating the relative intensity of the workout.

Important Notes

•

Remember, this is just for fun and to get an idea.

•

If you're not sure about working out, ask someone who's got the know-how, like a coach or a doctor.

•

Everyone's different, so don't expect to be as swole as your workout buddy overnight.

•

This is for learning, not replacing actual advice from someone who knows their stuff.
