Free fitness calculators and workout planning tools for macros, TDEE, protein, body measurements, strength, running pace and hydration.
DB's Workouts Fitness Tools Hub brings together 11 free browser-based tools for training, nutrition and progress tracking. It gives individuals and personal trainers one place to estimate practical targets and plan their next steps. The hub groups its tools into nutrition, body, hydration and training categories.
The Macro Calculator estimates daily calories and macronutrient targets. The TDEE Calculator estimates total daily energy expenditure from personal statistics and activity. The Protein Calculator helps users find a daily protein target for their goals. BMI and body fat calculators provide estimates for users reviewing body measurements; the body fat tool uses the US Navy method. These are estimates for planning and do not replace individual medical advice.
The hub includes a Water Intake Calculator with exercise and weather adjustments, a One Rep Max Calculator that estimates strength targets from repetitions and load, and a Running Pace Calculator that converts distance and time into pace splits. The Calorie Burn Calculator estimates energy expenditure for common activities using MET values.
An Outdoor Workout Generator creates a simple session from the equipment and time available. The Workout and Nutrition Plan generator provides a weekly training schedule and a daily nutrition blueprint. It is free and requires no login.
Open the Fitness Tools Hub, choose the relevant tool, enter the requested details and review the result. Users can return to the hub to move between calculators as their planning needs change. All tools in this collection are free to access online. This free hub is separate from the paid DB's Workouts app and its PT Pro features.
