BARBELL BACK SQUAT Form: Feet shoulder-width, knees track over toes, chest up, neutral spine, descend until hip crease below parallel, drive through midfoot to stand. Modifications: Reduce depth to 70-80% range of motion if lower back tightness persists | Use safety bar or tempo squats to build confidence | Front squat as alternative if posterior chain dominates Alternatives: Smith Machine Squat, Leg Press (higher back rest angle) BARBELL BENCH PRESS Form: Grip slightly wider than shoulder-width, shoulder blades retracted into bench, lower bar to mid-chest, drive with legs and chest, elbows at 45° angle from body. Modifications: Reduce range of motion with boards or pins if shoulder limited | Incline press shifts to anterior delts | Dumbbell press allows more natural shoulder angle Alternatives: Machine Chest Press, Dumbbell Bench Press CONVENTIONAL DEADLIFT Form: Shins vertical to bar at setup, neutral spine, shoulder blades over bar, drive knees forward initially, stand tall with squeeze at top, controlled descent with neutral spine throughout. Modifications: Reduce range of motion with elevated platform (deficit only if form is bulletproof) | Trap bar deadlift if lower back tightness worsens | Reduce frequency to 1x/week if persistent back strain Alternatives: Trap Bar Deadlift, Sumo Deadlift, Romanian Deadlift BENT-OVER BARBELL ROW Form: Hip hinge position (45° torso angle), neutral spine, chest to bar, elbows high and tight, row bar to lower chest, controlled eccentric with upper back tension. Modifications: Reduce range of motion with elevated platform if back tightness limits movement | Machine row if form breakdown occurs | Pendulum row for unloaded comfort Alternatives: Seal Rows (eliminates leg drive), Machine Rows, Yates Row (upright torso) EXERCISE MODIFICATIONS FOR LOWER BACK TIGHTNESS - Prioritize bracing and breathing cues before increasing load - Add 3-5min lower back mobilization (quadruped rockback,90/90 hip stretch, half-kneeling thoracic rotations) before each session - If pain (not tightness) occurs: reduce squat and deadlift frequency, swap for leg press/machine rows for 3-5 days - Avoid excessive ranges of motion during early sessions; build into full ROM over 2-3 weeks - Core strengthening: dead bugs 3×10, bird dogs 3×10ea, pallof press 3×12ea essential on all days PROGRESSIVE OVERLOAD CUES - Week 1-4: Master form, establish baseline loads - Week 5-8: Add 5-10lbs per week to compounds, increase reps on accessory work - Week 9-11: Add 2-5lbs per week to compounds, maintain accessory loads, emphasize RIR (reps in reserve) staying at 1-2 - Week 12: Assess 1RM estimates on primary lifts (bench, squat, deadlift); expect 8-15% strength gains if nutrition adequate SET/REP RPE GUIDE RPE 6 = 4 reps left in tank | RPE 7 = 3 RIR | RPE 8 = 2 RIR | RPE 9 = 1 RIR TEMPO NOTATION: 2-1-2 = 2sec eccentric, 1sec pause, 2sec concentric

PHASE 1 (Weeks 1-4): ANATOMICAL ADAPTATION Objective: Establish work capacity, learn movement patterns, baseline conditioning Progression Method: Add 2.5-5lbs per week to primary compounds (squat, bench, row, deadlift). Secondary lifts increase reps or slight load increases week-to-week. Example: Squat Week 1: 185lbs × 8 / Week 2: 190lbs × 8 / Week 3: 195lbs × 8 / Week 4: 185lbs × 8 (deload week built-in) PHASE 2 (Weeks 5-8): HYPERTROPHY Objective: Build muscle through moderate load and higher volume Progression Method: Add 5-10lbs per week to primary lifts. Accessory work: increase reps first (start week 5 rep targets), then load. Target 12-15 total reps per exercise via multiple sets. Example: Bench Week 5: 195lbs × 10 / Week 6: 205lbs × 10 / Week 7: 215lbs × 8-10 / Week 8: 195lbs × 10-12 (deload) Tracking: Use RPE 7-8; stop 2 reps short of failure to allow recovery and repeated stimulus weeks 5-8 PHASE 3 (Weeks 9-11): STRENGTH-HYPERTROPHY Objective: Peak strength while maintaining muscle; transition to lower reps, higher intensity Progression Method: Add 2-5lbs per week (smaller jumps preserve form at higher intensity). Primary compounds: 5×5, 4×6, 5×3 progressively heavier. Hit 8-9 RPE on final sets. Example: Squat Week 9: 225lbs × 5 / Week 10: 230lbs × 5 / Week 11: 235lbs × 5 (aim for near-max effort) Tracking: Estimated 1RM should increase 8-12% by week 11 based on load progression. Do NOT max out; use Epley formula (weight × (1 + reps/30)) to estimate if unsure WEEK 12: DELOAD Reduce volume 50% across all lifts. Use week 12 data as baseline for next 12-week block. Test 1RM lifts on Days 3 and 4 (deadline/row) if desired, but not required. Focus: recovery, form refinement, identifying weak points. FULL-PROGRAM PROGRESSION SUMMARY: Total Estimated Strength Gains: +8-15% on primary compounds (Squat, Bench, Deadlift, Row) Muscle Gain Estimate: +3-6lbs lean mass (assumes 0.8-1.2g protein/lb/day, +300-500kcal/day surplus) Deload Weeks: Week 4, Week 8, Week 12 built into structure; reduce volume 40-50%, maintain intensity (RPE), focus on recovery CUSTOMIZATION POST-12 WEEKS: - Repeat program with +5-10lbs starting loads (build on adaptations from phase 1-3) - OR transition to 8-week strength phase (3-4×3-5 on compounds, weekly maxes on day 1 & 3) - OR shift to upper/lower split if joint tightness improves; maintains 4-day frequency IF LOWER BACK TIGHTNESS PERSISTS: - Swap deadlift frequency to 1×/week (move to Day 1 or 3, alternate weeks) - Replace with Trap Bar Deadlift or add pause squats (pause alleviates lower back strain perception) - Increase front squat volume on Day 3 to balance posterior chain - Add 5-10min daily mobility work (couch stretch, 90/90 figure-4, quadruped rockbacks) - Reassess form; tightness often indicates stability deficits (weak core/glutes), not structural issues
