Plan your progressive overload with projected weights over weeks. Calculate weekly weight increases for linear, percentage-based, and undulating periodization models.
Progressive overload means gradually increasing training demand over time through load, reps, sets, or density.
This calculator lays out simple week-by-week progression using linear, percentage-based, or undulating models. It gives target weights for each week of a block and a projected endpoint.
Use it as a planning aid for a cycle rather than as a guarantee that progress will happen on schedule.
It is useful when you want a progression block mapped out instead of improvising loads week to week. The outputs are targets that still need to be adjusted for recovery, exercise selection, and actual performance.
Linear: Weight(n) = Starting Weight + (n × increment) Percentage: Weight(n) = Starting Weight × (1 + rate)^n Undulating: Alternates between light (~85%), medium (~92%), and heavy (~100%) of target for each week Projected 1RM (Epley): 1RM = weight × (1 + reps/30)
Result: 200 → 240 lbs over 8 weeks
Starting at 200 lbs with a 5 lb weekly increase over 8 weeks, your working weight progresses to 240 lbs. If training at 5 reps, your estimated 1RM goes from ~233 lbs to ~280 lbs — a 20% strength gain.
Muscle growth requires a stimulus that exceeds what the muscle is currently adapted to. This triggers a cascade of repair and adaptation processes (muscle protein synthesis, satellite cell activation, neural adaptations) that make the muscle stronger. Without progressive overload, there's no stimulus for further adaptation, and gains plateau.
Linear progression works fastest but has the shortest effective lifespan (3-12 months for most lifters). Percentage-based models sustain progression longer by making smaller jumps. Undulating periodization manages fatigue better and is often the best choice for intermediate and advanced lifters who train 3-4+ days per week.
When adding weight is no longer feasible, you can progress via: more reps (rep progression), more sets (volume progression), shorter rest periods (density progression), better technique (efficiency progression), or slower tempo (time under tension progression). The most effective programs use multiple overload variables strategically.

This worksheet turns a training rule into weekly set, rep, or rest planning guidance. It is meant for programming context rather than as an official protocol or medical rule.
For beginners: 5-10 lbs/week for lower body, 2.5-5 lbs/week for upper body. Intermediates: 2.5-5 lbs/week for lower, 1.25-2.5 lbs/week for upper. Advanced: 1-2.5 lbs/week if linear progression is still working. These rates slow as you advance.
Linear progression adds a fixed amount of weight to each workout or each week. It's the simplest and most effective model for beginners and early intermediates. Programs like Starting Strength and StrongLifts 5x5 are based on linear progression.
When linear progression stalls consistently (you can't hit your target weight/reps more than 2-3 sessions in a row). This usually happens after 6-12 months of training. Percentage-based models allow smaller, more sustainable increases.
Undulating periodization varies the intensity and volume within each week. Instead of always training heavy, you alternate between light (higher reps), medium, and heavy (lower reps) days. Research shows it produces similar or better results than linear periodization for intermediate+ lifters.
First, try repeating the weight for 1-2 more sessions. If still stalled: (1) take a deload week, (2) switch to a percentage-based model, (3) increase volume temporarily, (4) change exercise variations, or (5) improve recovery factors (sleep, nutrition, stress management).
Yes. Every 4-6 weeks, plan a deload where you reduce weight by 40-50% and volume by 30-50%. This allows accumulated fatigue to dissipate and often results in a performance jump the following week. Deloads are not optional for intermediate+ lifters.
