AI-built 3-day strength plan
12-16 weeks with 3 Full Body sessions each including squat, deadlift, bench and row. EntrenAI structures linear progression for beginners/intermediates + adaptive RPE. Frequency 3 each lift = better than traditional split for time-limited.
Updated
What is a 3-day strength plan?
The 3-day strength plan is designed for someone with limited time (professional, parent, student with tight schedule) who wants to gain real strength without dedicating 5-6 days/wk to gym.
Structure: Full Body 3×/wk with each session including:
- 1 heavy leg compound (squat or variant / deadlift)
- 1 heavy push compound (bench or military)
- 1 heavy pull compound (row or pull-ups)
- 2-3 complementary accessories
Why Full Body 3 days is optimal for time-limited:
- Frequency 3 each lift: superior to traditional split 1×/wk per group (Schoenfeld 2016 meta-analysis)
- Heavy compounds with 24-48h rest between: optimal neural recovery
- 60-75 min sessions: fits tight schedule
- Free days between sessions (typically Mon-Wed-Fri): functional social/family life
Differences vs 4-5-day plan:
- Lower total weekly volume (~12-15 sets/group vs 16-20 in 4-5 days)
- But higher frequency (3× vs 2×) partially compensates
- Result: ~85-90 % of 4-5-day plan progress with 60 % of time
The percentage of 1RM, session by session, for 3 days a week
Three sessions, each led by one lift (squat, bench press, deadlift) heavy with the other two light: every main lift is hit three times a week at three intensities.
- Heavy
- Medium
- Light
Your AI-generated plan
1. Initial validation.
- Cardiovascular health without restrictions
- No active lumbar/joint injuries
- Gym access with Olympic bar + squat rack
- 3 sessions/wk commitment, 60-75 min each
- No restrictions on doing squat, deadlift, bench
2. Typical weekly structure:
- Monday - Session A (squat + bench + row)
- Wednesday - Session B (deadlift + military + pull-ups)
- Friday - Session C (squat volume + bench volume + accessories)
3. Linear progression (beginner/intermediate):
- Squat: +2.5 kg each session (3×/wk = +7.5 kg/wk) for 4-6 wk
- Bench/Military: +1.25-2.5 kg each session
- Deadlift: +5 kg each initial session, then +2.5 kg
- 2 consecutive failed sessions: deload -10 % + restart
4. RPE for intermediates+:
- RPE 7-8 on main compound
- RPE 1-2 (RIR 1-2) on accessories
- Session C (volume) lighter: RPE 6-7 with more reps
5. 4-week periodization:
- Wk 1-3: linear progression + RPE 7-8
- Wk 4: deload -30 % volume, RPE 5-6
6. Exercise selection (each 8-12-week block):
Session A (Monday):
- Squat 4×5
- Bench press 4×5
- Pendlay row 4×6-8
- DB military press 3×8 (accessory)
- Plank 3×60s
Session B (Wednesday):
- Deadlift 3×5
- Barbell military press 4×5
- Pull-ups 4×max (weighted if capable)
- Bulgarian split squat 3×8/leg
- Barbell curl 3×10
Session C (Friday):
- Squat 5×3 @ slightly lighter (volume)
- Pause bench 4×6
- Barbell row 4×8
- Hip thrust 3×10
- Cable triceps 3×12
Which lift leads each day
Each session revolves around one main lift and is completed with two or three accessories that attack its weak point. This is how the app lays it out.

The rep table and the estimated 1RM
The engine estimates your 1RM with the Epley formula (weight × (1 + reps/30)) from every set you log, and from there works out the next weight. This plan works mostly in the marked range: 3-6 reps, 70-93%.
| Reps | % 1RM | 1RM 60 kg | 1RM 100 kg | 1RM 140 kg | 1RM 180 kg |
|---|---|---|---|---|---|
| 1 | 100 % | 60 kg | 100 kg | 140 kg | 180 kg |
| 2 | 96 % | 57.5 kg | 95 kg | 135 kg | 172.5 kg |
| 3 | 93 % | 55 kg | 92.5 kg | 130 kg | 167.5 kg |
| 4 | 90 % | 55 kg | 90 kg | 125 kg | 162.5 kg |
| 5 | 87 % | 52.5 kg | 87.5 kg | 122.5 kg | 157.5 kg |
| 6 | 85 % | 50 kg | 85 kg | 120 kg | 152.5 kg |
| 8 | 80 % | 47.5 kg | 80 kg | 112.5 kg | 145 kg |
| 10 | 75 % | 45 kg | 75 kg | 105 kg | 135 kg |
| 12 | 70 % | 42.5 kg | 70 kg | 97.5 kg | 125 kg |

Equipment needed
EntrenAI automatically substitutes any exercise if you don’t have the gear.
- Gym access with Olympic bar + squat rack + benches + dumbbells up to 25-30 kg
- Lifting belt (10 mm for intermediate)
- Flat shoes for squat and deadlift
- Chalk for deadlift
- Log app (Hevy, Strong, Boostcamp)
- Phone camera to occasionally film technique
- Optional wrist wraps + optional knee sleeves
What most people get wrong (and how to avoid it)
- 1
Wanting to do 4-5 days with 3-day plan
Only have 3 days? 3-day plan is optimized for that frequency. Adding 'extra session' on weekends = overtraining + no additional progression. Have 4-5 days? 4-5-day plan.
- 2
Skipping deadlift from injury fear
Deadlift is most important exercise for posterior strength + glutes + back. Skipping or substituting with light hip thrust = 30-50 % less progress. Weak technique? Start with light weight (50 % BW) and progress. Injury from properly executed deadlift is very rare.
- 3
Aggressive cardio on non-strength days
3-day plan requires recovery between sessions. HIIT or intense running on Tue/Thu compromises recovery. Short Z2 cardio (30-45 min) is OK, NO HIIT or running >60 min.
- 4
Not logging progression
Without log, you don't know if you're progressing. Lots of 'by feel' in 3-day plan = stagnation. Log app mandatory from session 1 — Hevy, Strong, Boostcamp, whatever.
- 5
Changing exercises every session
Same main exercises minimum 8-12 wk to produce progressive overload adaptation. Changing 'because boring' = lose investment. Vary accessories each block, NOT compounds.
- 6
Eating in caloric deficit
Strength plan in deficit loses 30-50 % effectiveness. Maintenance or slight surplus. Protein 1.8-2 g/kg, carb 4-5 g/kg, sleep 7-8h. Without this, plan delivers mediocre.
- 7
Skipping wk 4 deload
Deload (-30 % volume) is MANDATORY every 4 wk. Without deload, fatigue accumulates and plateau hits in wk 8-10. Supercompensation occurs in deload.
- 8
Squatting to parallel instead of below parallel
Valid competition squat = hip crease below knee line. Squat 'to parallel' or quarter-squat = incomplete work + many powerlifters/strength athletes consider it not done. EntrenAI requires full ROM. Limited mobility → goblet squat or box squat.

Frequently asked questions
Yes, clearly. For beginners/intermediates, 3 days Full Body produces 85-90 % of 4-5-day plan progress. Advanced saturate faster in 3 days — but up to 24-36 months on bar, 3 days is perfectly valid.
Loads rise 2.5-5 kg/wk per lift for 6-8 wk for beginner. Then slow progression (2.5 kg/2-4 wk). Visible muscle change in 8-12 wk + body composition in 12-16 wk (with adequate nutrition).
No for beginners/intermediates. Schoenfeld 2016 meta-analysis confirms frequency 3 superior to frequency 1. Total weekly load is distributed (12-15 sets/group in 3 sessions vs 16-20 in 4-5 sessions), recovery is viable.
When you've been 18-24 months progressing with 3-day plan + have available time + your goal is to maximize (not just progress). 4-day U/L or 5-day PPL allow more total volume = more advanced progress.
Not optimal — both highly fatiguing. EntrenAI separates them (Mon squat + Wed deadlift). Absolute limitation requires same day? Squat first + reduced deadlift (60 % normal load).
60-75 min including warm-up + session + cool-down. Systematically >90 min? You're resting too much between sets or doing excessive accessories. 90-150s rest between compound sets is optimal.
Creatine 5 g/day (proven for strength). Caffeine 200 mg pre-session optional. Whey/casein protein if difficult to reach 1.8 g/kg only with food. Nothing else needed for 3-day plan.
Deload indicator. Wk 1: -30 % volume, maintain relative intensity (RPE 6-7). Then resume with initial block loads. Still stuck after deload? Review nutrition + sleep.
