Periodization Planner

Plan volume and intensity progression across a training cycle using linear or undulating periodization. See weekly weight, set, and rep targets based on your 1RM.

simple

Plate Loading Calculator

Find the exact plate combination to reach your target barbell weight. Shows plates per side using standard plate sizes (45, 25, 10, 5, 2.5 lb).

simple

Wilks Score Calculator

Calculate your Wilks coefficient to compare powerlifting strength across body weight classes. Uses the official Wilks formula for both male and female lifters.

simple

Training Volume Calculator

Get recommended weekly sets per muscle group based on your experience level, goals, and training frequency. Uses volume landmarks (MV, MEV, MAV, MRV).

simple

Progressive Overload Calculator

Plan a 12-week weight and rep progression for compound lifts. See how gradually adding reps then weight drives volume increases over time.

simple

Muscle Balance Ratio Calculator

Evaluate your push/pull, quad/hamstring, and upper/lower strength balance. Identify weak points and reduce injury risk with ideal ratio analysis.

simple

Deload Week Calculator

Calculate reduced volume and intensity targets for your deload week. Choose between volume, intensity, or combined deload strategies for optimal recovery.

simple

Meet Attempt Selector

Plan your opener, second, and third attempts for a powerlifting meet. Get smart attempt selection based on your training maxes with projected totals.

simple

Band & Chain Calculator

Calculate effective loading at different positions when using bands and chains for accommodating resistance. See how load varies from bottom to lockout.

simple

Bodyweight Exercise Progression

Find your current level in calisthenics progressions and see estimated load for each difficulty tier. Covers push-ups, squats, and pull-ups from beginner to advanced.
