Progression Calculator
Calculate how many weeks it will take to reach your target weight for squat, bench press, and deadlift. Get a personalized periodized training plan with optimal workout routines designed to help you achieve your strength goals safely and effectively.
What This Calculator Does
The Progression Calculator helps you set realistic timelines for reaching your strength goals. Simply enter your current one-rep maxes for squat, bench press, and deadlift, along with your target weight (default 225 lbs), and the calculator will:
Calculate how many weeks you need to reach your target for each lift
Provide a weekly progression plan with specific weights, sets, and reps
Generate an optimal workout routine tailored to your timeline
Account for different progression rates between lifts (deadlifts progress slower than bench/squat)
The calculator uses periodization principles, starting with higher volume phases to build work capacity, then progressing to strength-focused phases, and finally peaking phases. This approach maximizes strength gains while minimizing injury risk.

Understanding Strength Progression
Strength progression follows predictable patterns, but the rate varies based on several factors:
Training Experience Level
- Novice: Can add 5-10 lbs per week initially
- Intermediate: Progresses 1-2.5 lbs per week consistently
- Advanced: Progresses 0.5-1 lbs per week or less
Lift-Specific Factors
- Bench Press: Often progresses fastest due to technical improvements
- Squat: Requires more leg strength development
- Deadlift: Progresses slowest due to higher recovery demands
Other Factors
- Age (peak strength years are 25-35)
- Training consistency and frequency
- Nutrition and recovery quality
- Sleep and stress management
- Genetic factors
Why Periodization Works
The calculator uses periodization - a systematic approach to training that varies volume and intensity over time. This method is proven to produce better results than training at the same intensity all the time.
Volume Phase (70-75% 1RM)
Builds work capacity, muscle mass, and technical proficiency. Higher reps (6-8) with moderate weight.
Strength Phase (80-85% 1RM)
Transitions from volume to strength. Moderate reps (4-5) with heavier weight to build maximal strength.
Intensity Phase (85-90% 1RM)
Focuses on heavy weights with lower reps (3-4) to build maximal strength and prepare for peak performance.
Peak Phase (90-95% 1RM)
Low volume, high intensity work (1-3 reps) to peak for your target weight. This phase is short to avoid burnout.
Pro Tip: Deload Weeks
Every 4th week should be a deload week where you reduce volume by 40-50% while maintaining intensity. This allows your body to recover, reduces accumulated fatigue, and sets you up for stronger performance in the next training block. Don't skip deloads - they're an investment in long-term progress.
Tips for Success
- Be consistent - Follow your plan and train 2-3 times per week per lift
- Track your progress - Use the JustGains app to log your workouts and see your strength progression over time
- Prioritize recovery - Get 7-9 hours of sleep, eat enough protein (0.8-1g per lb bodyweight), and manage stress
- Focus on form - Perfect technique is more important than adding weight quickly
- Include accessories - Target weak points with 2-3 accessory exercises per session
- Be patient - Strength gains take time. Trust the process and adjust based on your actual progress
- Don't skip deloads - Recovery weeks are essential for long-term progress
