4-Day Upper/Lower Strength Program — Muscle Preservation

4-Day Upper/Lower Strength Program

Goal: Maintain strength and muscle while reducing body weight
Schedule: Monday / Tuesday / Thursday / Friday
Split: Upper / Lower / Upper / Lower
Session limit: ~60 minutes
Primary focus: Heavy compound lifts, moderate volume, high effort, sustainable progression

Important: If you are under 18, don’t intentionally restrict calories or pursue weight loss without guidance from a parent/guardian and a qualified healthcare professional. This program is written around strength and general fitness rather than aggressive dieting.

Weekly Schedule

Day	Session	Main emphasis
Monday	Upper A	Horizontal press + row
Tuesday	Lower A	Squat + posterior chain
Wednesday	Rest	Recovery
Thursday	Upper B	Vertical press + vertical pull
Friday	Lower B	Hinge + unilateral/secondary squat
Saturday	Rest	Recovery
Sunday	Rest	Recovery

Training Principles

• Main compounds: Mostly 4–6 reps.
• Secondary compounds: Mostly 6–8 reps.
• Accessories: Mostly 8–12 reps.
• Keep most working sets at ~1–3 reps in reserve (RIR). Avoid regularly training to failure on heavy compounds.
• Rest 2–3 minutes on the main lifts and 90–120 seconds on secondary lifts.
• When time is tight, prioritize the first 3–4 exercises rather than rushing every movement.
• The two weekly exposures use different exercises or variants while still training the same major muscle groups.
• During a calorie deficit, the goal is primarily to maintain performance, not to add large amounts of training volume.

Progression

Use double progression rather than forcing weight increases every session.

Main lifts

For exercises using a 4–6 rep range:

1. Choose a weight you can perform for about 4 reps while keeping ~2 RIR.
2. Keep the same weight until you can perform 6 reps on every working set with good technique and the intended RIR.
3. Increase the load by the smallest practical increment.
4. Repeat.

Example:

Week 1: 100 kg — 6 / 5 / 5
Week 2: 100 kg — 6 / 6 / 5
Week 3: 100 kg — 6 / 6 / 6
Week 4: 102.5 kg — 4 / 4 / 4

Secondary lifts

For exercises using 6–8 reps:

• Increase the load once all working sets reach 8 reps at the intended RIR.
• Then return toward the lower end of the rep range and build back up.

Accessories

For 8–12 reps:

• Add reps before adding weight.
• Use small load increases when you can complete all sets at 12 reps with good technique.

Effort During a Cut

The priority order should be:

1. Keep technique consistent.
2. Maintain strength as well as practical.
3. Keep weekly training volume manageable.
4. Avoid adding extra work simply to burn more calories.

Some performance fluctuation is normal when recovering from a calorie deficit. A small reduction in reps or load on difficult weeks does not automatically mean muscle has been lost.

If recovery deteriorates, reduce accessory volume before cutting back the main compound lifts.

---

Time Management

To stay within 60 minutes:

0–8 min

General warm-up + specific warm-up sets

8–35 min

First two major compound movements

35–50 min

Secondary compounds

50–60 min

Accessories/core

You can alternate non-competing accessories to save time, for example:

• Lateral raises ↔ curls
• Triceps pressdowns ↔ lateral raises
• Calf raises ↔ core work

Do not rush heavy compound sets just to stay on schedule.

Exercise Substitution Rules

If equipment or comfort requires a substitution, preserve the movement pattern rather than the exact exercise.

Original	Suitable alternatives
Back Squat	Hack Squat, High-Bar Squat
Front Squat	Safety-Bar Squat, Leg Press
Bench Press	Dumbbell Bench Press, Machine Chest Press
Incline Dumbbell Press	Incline Barbell Press, Incline Machine Press
Barbell Row	T-Bar Row, Chest-Supported Row
Chest-Supported Row	Seated Cable Row, Machine Row
Pull-Up	Lat Pulldown
Romanian Deadlift	Stiff-Leg Deadlift, Machine/Smith RDL
Conventional Deadlift	Trap-Bar Deadlift
Bulgarian Split Squat	Reverse Lunge, Step-Up
Leg Curl	Seated or Lying Leg Curl

---

Recovery

• Keep at least one full rest day between the Tuesday and Thursday sessions.
• Aim for consistent, sufficient sleep.
• Eat regular, balanced meals and include a protein source with meals.
• Stay hydrated.
• Don’t add large amounts of cardio or extra lifting if it interferes with recovery or strength.

Deload / Fatigue Management

A deload is not mandatory on a fixed schedule.

Consider reducing training stress for about a week if several of these occur together:

• Performance is declining across multiple sessions.
• Normal loads feel substantially harder than usual.
• Technique is deteriorating.
• Persistent soreness is interfering with training.
• Motivation and recovery are noticeably worse.

A simple deload:

• Keep the same exercises.
• Reduce working sets by roughly one-third to one-half.
• Keep loads moderate and stop several reps before failure.

Then resume normal training gradually.

Key Rules

• Don’t chase fatigue. Chase performance.
• Heavy compounds come first.
• Keep most compound sets at 1–2 RIR.
• Progress when you earn the top of the rep range.
• During a cut, maintaining strength is a successful outcome.
• Keep sessions to roughly 60 minutes rather than adding unnecessary volume.
