IPF Raw Bench Press — The International Powerlifting Federation (IPF) governs world-level raw powerlifting. Below are approximate all-time world records for reference. Raw means no supportive equipment — only belt, wrist wraps, and singlet are allowed.

Equipped vs. Raw: Equipped bench press (with a bench shirt) typically adds 20-40% to a lifter's raw total. World-class equipped bench pressers have exceeded 700+ kg.

Setup Checklist
1
Foot Position: Plant feet flat on the floor (or on a platform). Drive through heels to create full-body tension via leg drive.
2
Scapular Retraction: Pinch shoulder blades together and depress them (pull down and back). This creates a stable base and shortens the pressing distance.
3
Arch: A natural arch is legal and reduces ROM. Maintain glute contact with the bench throughout the lift (IPF rule).
4
Bar Path: Lower the bar to your lower chest/nipple line at a slight diagonal. Press back up and slightly back toward your face — not straight up.
5
Wrist & Elbow: Keep wrists straight (bar over heel of palm). Tuck elbows to ~45-75° from your torso — flaring elbows risks shoulder impingement.
Grip Width Estimator

Enter your biacromial width (distance between shoulder joints) to calculate recommended grip spacing on the bar.

Tip: Measure from left to right shoulder joint (acromion to acromion) with a measuring tape.

Frequently Asked Questions

How accurate is the 1RM estimate?

Accuracy depends heavily on rep count. Sets of 1-5 reps give estimates within 2-5%. Sets of 6-10 reps carry 5-8% error. Above 10 reps the error can reach 10-15% due to fatigue and individual muscle fiber type differences. For the best estimate, test with 2-5 reps on a near-maximal set.

Why is my paused bench lower than my touch-and-go?

Touch-and-go bench uses the stretch-shortening cycle (SSC) — the elastic energy stored as the bar compresses your chest bounces it back up. Paused bench eliminates this, making it approximately 3-6% harder. Most competitive powerlifters compete with a mandatory pause, so the paused 1RM is the true measure of raw pressing strength.

What is a Wilks score and what is a good score?

The Wilks score (updated 2020) is a bodyweight-normalized strength coefficient that allows lifters of different sizes to be compared. For bench press alone, scores above 80 indicate strong novice performance, 100-120 is competitive, and 150+ is elite/national-level. World-class bench pressers often exceed 200 Wilks.

What is Smolov Jr and is it safe?

Smolov Jr is a 6-week Russian bench press specialization program that uses very high frequency (4 sessions per week) to rapidly increase bench press. Lifters commonly report 10-30 lbs gains in one cycle. It is intense and not recommended for beginners. You should be at least an intermediate lifter (bench 1.25x bodyweight) before attempting it, and avoid other heavy upper body work during the cycle.

What is a good bench press by body weight?

For males: Untrained = 0.5x BW, Beginner = 0.75x, Novice = 1x, Intermediate = 1.25x, Advanced = 1.5x, Elite = 1.75x, World Class = 2x+. For females, standards are approximately 50-60% of male standards. Reaching 1x bodyweight is a common first milestone, while 1.5x signifies serious strength training progress.

What is a Training Max (TM) and how should I use it?

A Training Max is 90% of your estimated 1RM. Programs like 5/3/1 (Wendler) and Juggernaut use the TM rather than the true 1RM to ensure all programmed sets are achievable and to build in a buffer against daily performance variation. Using TM also keeps volume manageable for recovery.

Close grip vs. wide grip — which builds more strength?

Wide grip reduces the range of motion (ROM) and emphasizes the chest, while close grip increases ROM and shifts work to the triceps. Most powerlifters use a medium-to-wide grip (1.5-1.8x shoulder width) for maximal weight. Close-grip bench is an excellent accessory for triceps strength and lockout improvement. The "best" grip is individual and depends on your limb proportions and weak points.

1RM Formulas Explained

All four formulas take the same inputs: weight (w) lifted for (r) repetitions.

Epley (1985)
1RM = w × (1 + r / 30)
Most widely used. Slightly overestimates at high rep counts. Best for 1-5 reps.
Brzycki (1993)
1RM = w × 36 / (37 - r)
Extremely accurate for 1-10 reps. Undefined for r ≥ 37 (a limitation at very high reps).
Mayhew et al. (1992)
1RM = (100 × w) / (52.2 + 41.9 × e^(-0.055 × r))
Exponential model validated in peer-reviewed research. Most accurate for 6-10 rep sets.
Lombardi (1989)
1RM = w × r^0.1
Conservative and tends to underestimate at high rep counts. Useful as a lower-bound estimate.
Style & Grip Corrections
Adjusted 1RM = Raw 1RM × Style Factor × Grip Factor
Example: Paused (×1.04) + Close Grip (×1.09) = ×1.134 total correction to get flat standard equivalent.
Wilks Score (2020)
Wilks = (600 / polynomial(BW)) × lift(kg)
5th-order polynomial with sex-specific coefficients. Normalizes strength to bodyweight.

Key Terms

1RM
One-Rep Maximum. The maximum weight you can lift for exactly one complete repetition with proper form.
Training Max
90% of your 1RM. Used as the base for percentage-based programs like 5/3/1 to provide a buffer for bad days and ensure all sets are achievable.
RPE
Rate of Perceived Exertion on a 1-10 scale. RPE 10 = maximum effort / no reps left. RPE 8 = 2 reps in reserve (RIR). Important for autoregulation in programming.
Wilks Score
A formula for comparing lifters of different body weights. Higher Wilks = stronger relative to body weight. Updated in 2020 with improved coefficients.
DOTS Score
IPF's 2019 alternative to Wilks. Uses a different polynomial formula that provides better balance across weight classes, especially at heavier body weights.
Paused Bench
Bar held motionless on the chest (or just above) before pressing. Eliminates elastic energy from the stretch-shortening cycle, making it 3-6% harder than touch-and-go.
Touch-and-Go
Bar lightly touches chest and is immediately pressed back up, using the stretch-shortening cycle. Not valid in raw powerlifting competition.
Scapular Retraction
Squeezing shoulder blades together and pulling them down. Creates a stable platform for pressing and reduces shoulder impingement risk.
Leg Drive
Actively pressing feet into the floor to create full-body tension through the arch. Transfers force from the lower body through the torso to enhance pressing strength.
Biacromial Width
The distance between the acromion processes (tips of shoulder joints). Used to calculate optimal grip width: standard = 1.5x biacromial, wide = 1.8x.
5/3/1
Jim Wendler's percentage-based programming system using 3 main sets per session with a + set (as many reps as possible). Widely used for long-term strength building.
Smolov Jr
A 6-week bench press specialization from Russian powerlifting tradition. 4 sessions/week at high volume. Produces rapid strength gains but requires full recovery focus.

The Complete Guide to Bench Press Programming

Why Test Your 1RM?

Knowing your one-rep maximum is the cornerstone of intelligent programming. Almost all percentage-based programs (5/3/1, Smolov, Texas Method, Cube Method) require knowing your 1RM to calculate working weights. Regularly testing or estimating your 1RM also provides objective feedback on your progress and helps identify when a programming change is needed.

Choosing the Right Formula

For most lifters, the 4-formula average gives the most robust estimate. If you regularly perform near-maximal sets of 1-5 reps, Epley or Brzycki are excellent choices. Competitive powerlifters who test with 6-10 rep sets should consider the Mayhew formula, which was validated specifically for this rep range. Avoid using any formula with more than 15 reps — the error becomes too large for practical use.

Programming for Strength: 5/3/1

Jim Wendler's 5/3/1 is the gold standard for intermediate-to-advanced lifters. Based on your Training Max (90% of 1RM), you cycle through three main sets per session (5/5/5+, 3/3/3+, 5/3/1+) across four weeks before deloading. The + sets are crucial — perform as many reps as possible to drive adaptation. Add 5 lbs to your bench TM each cycle for slow, sustainable progress.

Smolov Jr for Rapid Gains

If you need to make rapid bench press gains — for a competition, a bet, or just to break a plateau — Smolov Jr is the most proven specialization program. Over 6 weeks, you'll press 4 days per week at high frequency and volume. Most lifters add 10-30 lbs in a single cycle. The cost is significant fatigue, so scale back all other pressing during the program and prioritize sleep and nutrition.

The Importance of Technique

Technical mastery can add 10-20% to your bench press without any increase in muscle mass. Key technique upgrades: (1) Develop leg drive — it contributes 15-20% of pressing force in elite lifters. (2) Achieve proper scapular retraction and depression before unracking. (3) Find your optimal bar path — slightly diagonal from lower chest to above your eyes. (4) Tuck your elbows to a sustainable angle (45-60°) that balances shoulder health with mechanical advantage.

Common Bench Press Mistakes

1. Bouncing the bar — reduces tension and risks injury. Control the descent. 2. Lifting the hips — illegal in competition, reduces stability. 3. Flaring elbows — compresses the shoulder joint. 4. Not pausing — touch-and-go can mask weakness. Include paused work. 5. Neglecting the upper back — rows, pull-ups, and face pulls are essential for shoulder health and pressing power.
