Reg Park’s Original 5×5 Routine

Reg Park’s program revolves around three workout days per week, with a mix of squats, deadlifts, and pressing exercises. You’ll be focusing on total-body lifts for functional muscle and power, adding weight every workout to push for constant progression.

The Weekly Layout

Day Exercise Sets x Reps Notes
Monday Squat 5 x 5 Heavy, full-depth squats with progressive loading.
Bench Press 5 x 5 Use a controlled, powerful press technique.
Barbell Row 5 x 5 Focus on squeezing shoulder blades for back strength.
Wednesday Squat 5 x 5 Light day with 70-80% of Monday’s weight.
Overhead Press 5 x 5 Full lockout, strong core engagement.
Deadlift 5 x 5 Go heavy; perfect form to avoid injuries.
Friday Squat 5 x 5 Return to Monday’s weight, or increase by 5-10 lbs.
Bench Press 5 x 5 Aim to add weight from Monday’s workout.
Barbell Row 5 x 5 Progressively load from Monday’s session.

Pro Tip: Rest for 2-3 minutes between sets. This is essential to maintain form and strength as the weights get heavy.


Key Exercises in the 5×5 Program

Each movement in Reg Park’s 5×5 plan hits the big muscle groups, recruiting multiple muscles for strength and muscle density. Here’s why each exercise matters.

  1. Squats
    • Primary Muscles Worked: Quads, Glutes, Hamstrings, Core
    • The squat is the backbone of any strength routine. Full-depth squats activate every muscle from your legs to your core, driving strength gains and improving flexibility. Start with a weight you can handle and work up gradually.
  2. Bench Press
    • Primary Muscles Worked: Chest, Shoulders, Triceps
    • The bench press is the gold standard for upper body strength. A proper 5×5 bench press targets the entire chest and triceps, enhancing pushing power for both aesthetic and functional gains.
  3. Barbell Row
    • Primary Muscles Worked: Upper Back, Lats, Biceps
    • Barbell rows build back thickness and stability, which supports other heavy lifts. Focus on pulling with your elbows and squeezing at the top to maximize back activation.
  4. Overhead Press
    • Primary Muscles Worked: Shoulders, Triceps, Core
    • The overhead press rounds out upper body strength by hitting the deltoids and triceps hard. It’s also a core exercise, as your core must brace to stabilize the press overhead.
  5. Deadlift
    • Primary Muscles Worked: Hamstrings, Glutes, Back, Core
    • The deadlift is the ultimate test of strength. This lift activates the posterior chain (everything from your hamstrings to your upper back), helping you generate full-body power and reinforcing functional strength.

Tips for Getting the Most Out of Reg Park’s 5×5

  1. Prioritize Form: Proper form is king in a 5×5 program. With heavy weights, even slight misalignments can lead to injuries. Focus on mastering technique, and if needed, start with a lighter weight to get it right.
  2. Progress Slowly but Consistently: Aim to add 5-10 pounds per week to your lifts. Small, steady increases compound over time, building significant strength and muscle gains.
  3. Rest Well Between Sets: With only 5 reps per set, you’re lifting heavy. Allow your muscles to recover between sets with 2-3 minute breaks to sustain power throughout the workout.
  4. Eat for Strength: To see gains, you need fuel. A high-protein, high-carb diet supports muscle recovery and growth, while ensuring you have the energy to lift heavy week after week.
  5. Take Deload Weeks: Every 4-6 weeks, reduce weights by 20-30% for one week to allow your muscles and central nervous system to recover.

Sample Reg Park 5×5 Progression Chart

Here’s a sample of how you might progress over six weeks, assuming a starting squat weight of 225 lbs.

Week Squat (5×5) Bench Press (5×5) Barbell Row (5×5) Overhead Press (5×5) Deadlift (5×5)
1 225 lbs 135 lbs 135 lbs 95 lbs 225 lbs
2 230 lbs 140 lbs 140 lbs 100 lbs 235 lbs
3 235 lbs 145 lbs 145 lbs 105 lbs 245 lbs
4 240 lbs 150 lbs 150 lbs 110 lbs 255 lbs
5 245 lbs 155 lbs 155 lbs 115 lbs 265 lbs
6 250 lbs 160 lbs 160 lbs 120 lbs 275 lbs

Note: Progression will vary based on individual strength levels and recovery. Listen to your body and adjust weight increases if necessary.


Common Mistakes to Avoid

  1. Going Too Heavy, Too Soon: Ego lifting is a quick route to injuries. Start with a manageable weight and focus on perfecting form before adding weight.
  2. Skipping Rest Days: Your muscles need time to repair and grow stronger. Stick to the three-day-per-week schedule and resist the urge to train every day.
  3. Ignoring Diet: The 5×5 routine demands fuel. If you’re not eating enough protein and carbs, you’ll plateau quickly. Aim for 1g of protein per pound of body weight daily.
  4. Neglecting Warm-Ups: Warming up prepares your body for heavy lifts. Spend 5-10 minutes doing dynamic stretches or light cardio before each session.

FAQ: Crushing the Reg Park 5×5 Routine

  • How much weight should I start with?
    • Begin with about 70% of your 1-rep max. For example, if you can squat 315 lbs for one rep, start your 5×5 sets around 225 lbs.
  • Can I add extra exercises?
    • Keep it simple. Adding more exercises can lead to overtraining. Stick to the core lifts to maximize recovery and strength gains.
  • How do I handle plateaus?
    • If you hit a wall, take a deload week where you reduce the weights by 20%. Return to your regular weights the following week.

Bottom Line

The Reg Park 5×5 Strength Routine isn’t about fancy machines or endless exercises. It’s about raw, functional strength. Stick to the basics, lift heavy, and watch your power and size climb.
