How to Train Bench Throw Power: An 800Hz IMU Protocol for Upper-Body Explosiveness

The bench press is the gold standard for upper-body strength — but it has a critical ceiling for power. In a normal bench press the lifter decelerates the late portion of the lift to keep the bar in their hands. That deceleration teaches the nervous system to brake and caps power output. Newton et al. (1996) found acceleration occupies only ~50% of the bench press range, while the bench throw extends acceleration to 96%.

The bench throw is a ballistic bench press: the lifter intentionally launches the bar, and a catch system retrieves it safely. This single change rewires the neuromuscular stimulus — deceleration learning is removed, and propulsive intent runs to 100%. The PoinT GO 800Hz IMU records launch velocity, power, and propulsive time, making bench throw training fully quantifiable. This guide covers safety, an 8-week protocol, and the key metrics. Pair it with our bench press velocity zones.

Ballistic training spans any movement that ends in projection — jumps for the lower body, throws for the upper body. The defining contrast with traditional resistance work is the acceleration profile. A normal bench press at 80% 1RM accelerates for 60–70% of the rep; a bench throw at the same load accelerates for 95%+, with maximal intent maintained to release.

Cronin et al. (2003) compared 12 weeks of bench throws vs. traditional bench in trained athletes. The bench throw group gained 18.4% more upper-body power. 1RM gains were similar (11.2% vs 12.1%), proving bench throws add power without sacrificing strength.

The bench throw is the only option that develops both 1RM and power, which is decisive for comprehensive upper-body capacity.

Safety is the gating constraint. Three validated systems exist.

1. Smith machine catch. The bar runs in fixed rails, providing predictable catches. Stability is high but free acceleration is constrained — appropriate for beginners. 2. Power rack + pin catch. Set safety pins 5 cm above the peak of the bar's flight. Combines free-bar acceleration with engineered safety — ideal for intermediate and advanced lifters. 3. Spotter team catch. Two spotters on either side capture the bar. Maximum freedom but requires expert spotting.

Across all systems, hold loads to 30–50% 1RM. Heavier loads shorten flight distance, defeating the ballistic stimulus and increasing risk. Use a firm bench pad and lock the scapula in retraction-depression to protect the shoulder. Pre-screen capacity with the plyometric push-up test.

This protocol pairs progressive loading with launch velocity gates. Weeks 1–2 (adaptation): 30% 1RM, 4 sets x 5 reps, target launch velocity above 1.4 m/s. The objective is catch system mastery.

Weeks 3–4 (velocity development): 35% 1RM, 5 x 4, target above 1.3 m/s. Rest 2:30 between sets for full recovery. Weeks 5–6 (force-velocity integration): 40% 1RM, 5 x 4, target above 1.2 m/s — cut the set the moment velocity drops below target.

Weeks 7–8 (peak): 45% 1RM, 4 x 3, target above 1.1 m/s. Add a single 50% 1RM test set in the final week. Run 2 sessions/week, on different days from heavy bench (80–90% 1RM). Average launch velocity gains 0.18–0.24 m/s over 8 weeks. Use our 1RM calculation methods to set the right loads.

Five core metrics: launch velocity, peak power, mean power, throw height, and asymmetry. Norms below reflect 80 kg male athletes.

Asymmetry above 7% raises injury risk and warrants unilateral work (DB throws, single-arm med-ball chest pass). Track asymmetry over time with the medicine ball throw test.
