Lyle McDonald designed this routine and published it on his bodyrecomposition.com forums around 2008-2009. It was later compiled and popularized through JCDFitness.
The core principle: training each muscle group twice per week with moderate volume and progressive overload is the most efficient way to grow during a bulk. Lyle specifically designed the routine to sit between low-volume approaches like Doggcrapp and high-volume bodybuilding splits. Enough stimulus per session to trigger growth, but not so much that you can't recover for the second session that week. Progressive tension overload (adding weight to the bar) is the primary driver of growth, with metabolic stress from higher-rep sets as a secondary stimulus.
Who It's For
Experience level: Intermediate (1-3 years of consistent training). You should be comfortable with Squat, Bench Press, Stiff Leg Deadlift, and Bent Over Row form.
Primary goal: Hypertrophy with strength as a secondary benefit.
Best suited for: Bulking phases with a caloric surplus of 250-500 calories above maintenance, aiming for 0.5-1lb of weight gain per week. Not ideal for cutting since the volume will be hard to recover from in a deficit.
Pros & Cons
Pros
Twice-per-week frequency per muscle group matches what research supports as optimal for hypertrophy
Three distinct rep ranges (6-8, 10-12, 12-15) provide both mechanical tension and metabolic stress
Simple structure with only two unique workouts, easy to learn and track
Low isolation volume (2 sets each for biceps and triceps) keeps sessions to about 60-70 minutes
Flexible set ranges (3-4, 2-3, 1-2) let you auto-regulate based on daily readiness
Cons
No direct ab, rear delt, or lateral delt work. You'll need to add these yourself
Repeating the exact same workout twice per week can feel monotonous after several cycles
Squat and Stiff Leg Deadlift back-to-back on lower days is fatiguing, and the SLDL suffers
No built-in deload protocol. You need to self-manage fatigue over the 6-8 week cycle
Program Structure
Split: Upper/Lower
Periodization: Double progression (add reps within range, then add weight)
Schedule: Fixed weekly, Mon/Tue/Thu/Fri (with Wed and weekends off)
Both lower body days are identical, and both upper body days are identical. Lyle suggests optionally varying exercises on the second session of the week (see Common Modifications).
Exercise Selection & Rationale
Lower Body follows a quad-dominant, hip-dominant, quad-accessory, hamstring-accessory, calf pattern. Squat is the primary quad compound at heavy weight. Stiff Leg Deadlift provides heavy hip-hinge work and stretches the hamstrings under load. Leg Press adds quad volume at moderate reps without the spinal fatigue of more squatting. Seated Leg Curl isolates the hamstrings through knee flexion (complementing the SLDL which works them through hip extension). Two calf exercises: Standing Calf Raise hits the gastrocnemius (straight-knee), Seated Calf Raise targets the soleus (bent-knee).
Upper Body alternates push/pull movements. Bench Press is the primary horizontal press. Bent Over Row is the primary horizontal pull, balancing the bench volume. Shoulder Press (dumbbell) adds vertical pressing volume at moderate reps. Lyle lists this as interchangeable with Incline Bench Press, Dumbbell. Chin Up covers vertical pulling and adds bicep work. Skullcrusher and Hammer Curl provide direct arm work at high reps to round out the session.
Substitution options: Stiff Leg Deadlift can be swapped for Romanian Deadlift, Barbell. Shoulder Press can be swapped for Incline Bench Press, Dumbbell or Overhead Press. Chin Up can be replaced with Lat Pulldown or Pull Up. Hammer Curl can be swapped for Bicep Curl, Barbell or Bicep Curl. Skullcrusher can be swapped for Triceps Pushdown or Triceps Extension, Cable.
Set & Rep Scheme
The program uses three tiers of set/rep ranges, each targeting a different adaptation:
Main compounds (Squat, Stiff Leg Deadlift, Bench Press, Bent Over Row, Standing Calf Raise): 3-4 sets of 6-8 reps. Heavy enough to build strength and create high mechanical tension, the primary driver of hypertrophy.
Secondary compounds (Leg Press, Seated Leg Curl, Shoulder Press, Chin Up, Seated Calf Raise): 2-3 sets of 10-12 reps. Moderate weight accumulates volume and metabolic stress without the CNS drain of heavy sets.
Isolation (Skullcrusher, Hammer Curl): 1-2 sets of 12-15 reps. High reps with shorter rest periods for a pump. Arms already get significant indirect work from the compound movements, so direct volume is kept low.
Lyle recommends starting on the lower end of set ranges and adding sets as your work capacity improves. If the routine feels like too much, drop to 2-3x6-8 and 1-2x10-12.
Progressive Overload
This implementation uses double progression for all exercises:
Start at the bottom of your rep range (e.g., 6 reps for a 6-8 range).
Each session, try to add reps: 4x6 -> 4x7 -> 4x8.
Once you hit the top of the range on all sets, add 5lb and reset to the bottom.
For example, Squat starts at 4x6. You work up to 4x8. Once you complete 4x8, the weight goes up by 5lb and you drop back to 4x6.
When you stall: If you can't add reps for 2-3 sessions, reduce weight by 10% and build back up. Lyle also recommends running the program in 6-8 week cycles, then taking a deload week (reduce volume by 40-50%) before starting a new cycle.
Recommended cycle structure: Lyle suggests 8-week cycles. Weeks 1-2 are a "submaximal run-up" using 85-95% of your working weights to ease in. Weeks 3-8 are full-effort progressive overload. Then deload and start a new cycle with slightly higher baseline weights.
How Long to Run It / What Next
Run for 6-8 weeks per cycle, with a deload week between cycles. You can repeat cycles for as long as you're in a caloric surplus and still progressing, typically 3-6 months during a dedicated bulk.
Signs it's time to move on: You're stalling on most exercises despite deloading, you're no longer in a surplus, or you want more variety. Transition to PHUL (adds separate power/hypertrophy days), a PPL split (6 days/week for more volume), or 5/3/1 BBB (if you want to shift toward strength).
Equipment Needed
Barbell, dumbbells, leg press machine, seated leg curl machine, standing calf raise machine (or smith machine), seated calf raise machine.
Home gym substitutions:
Leg Press -> Bulgarian Split Squat or Front Squat
Seated Leg Curl -> Romanian Deadlift or Good Morning
Standing Calf Raise -> Standing Calf Raise, Bodyweight (on a step with added weight)
Seated Calf Raise -> Seated Calf Raise, Dumbbell
Chin Up works as-is for home gyms with a pull-up bar
Rest Times
6-8 rep exercises (Squat, Stiff Leg Deadlift, Bench Press, Bent Over Row, Standing Calf Raise): 3 minutes
For each exercise, pick a weight where you can complete all prescribed sets at the bottom of the rep range with 1-2 reps in reserve. For example, if the prescription is 4x6-8, choose a weight you could do for about 9-10 reps to failure. This gives you room to progress within the range.
If you don't know your rep maxes: Start conservatively. Use roughly 70-75% of what you think you could do for a heavy single. It's always better to start too light since the double progression will bring you up to the right working weights within 2-3 weeks.
Common mistake: Starting too heavy and immediately hitting the top of the rep range. This leaves no room for progression and defeats the purpose of double progression.
Common Modifications
Vary the second session: On the second Lower day, swap Squat for Deadlift or Front Squat and use Leg Press as the primary 6-8 rep movement. On the second Upper day, swap Bench Press for Incline Bench Press and Bent Over Row for Lat Pulldown or Pull Up.
Add rear delts: Face Pull or Reverse Fly for 2-3x15-20 at the end of upper body days. The program has zero direct rear delt work.
Add abs: Hanging Leg Raise or Cable Crunch for 2-3 sets at the end of lower body days.
Add lateral delts: Lateral Raise for 2-3x12-15 at the end of upper body days.
Strength/hypertrophy variant: Run the first session each week at 3-5x5 (strength focus) and the second session at 3x8-12 (hypertrophy focus). Lyle mentioned this as a valid long-term periodization approach.
Reduced volume: If recovery is an issue, drop to 2-3x6-8 for main compounds and 1-2x10-12 for secondary lifts.
Frequently Asked Questions
Is Lyle's Generic Bulking good for beginners?
No, it's designed for intermediate lifters with 1-3 years of training experience. You should be comfortable with squat, bench, deadlift, and row form. If you're still making session-to-session progress, use a beginner program like GZCLP first.
