Workout Description

Why This Workout Is Hard

The weighted strict pull-ups are highly demanding for grip and upper body strength, while 100ft of front-racked lunges creates significant leg fatigue and core demands. As a 20-minute AMRAP with no built-in rest, fatigue accumulates severely - grip exhaustion from pull-ups directly impacts the ability to hold dumbbells for lunges. The continuous nature and movement interference make this substantially harder than either movement would be in isolation.

Training Focus

This workout develops the following fitness attributes:

• Stamina (8/10): Weighted strict pull-ups will quickly exhaust grip and pulling stamina, while lunges create leg muscular endurance demands over extended time.
• Endurance (7/10): Twenty minutes of continuous work with weighted movements creates significant cardiovascular demand, requiring sustained aerobic capacity to maintain output.
• Strength (6/10): 50/35 lb dumbbells require moderate strength for strict pull-ups and front-racked lunges, testing both upper body and core strength.
• Speed (5/10): AMRAP format rewards efficient transitions and consistent pacing, though heavy weights limit cycling speed compared to bodyweight movements.
• Flexibility (4/10): Front-racked position demands shoulder and thoracic mobility, while lunges require hip flexor and ankle flexibility for proper depth.
• Power (2/10): Strict pull-ups eliminate momentum and lunges are controlled movements, making this primarily a strength-endurance rather than power workout.

Movements

• Dumbbell Front Rack Walking Lunge
• Weighted Strict Pull-Up

Scaling Options

Reduce weight to 35/25 lbs or 25/15 lbs. Substitute banded strict pull-ups, ring rows, or jumping pull-ups with slow negative. Reduce pull-ups to 4-5 reps. Shorten lunges to 50ft if space limited. Consider single dumbbell front-loaded goblet lunges for those struggling with dual DB coordination.

Scaling Explanation

Scale if you cannot perform 3+ strict pull-ups unweighted or if dumbbells feel heavy for overhead press. Goal is continuous movement for 15+ minutes with brief rests only. Prioritize strict pull-up form over weight - better to use assistance and maintain strict movement than compromise to weighted kipping.

Intended Stimulus

Moderate aerobic capacity workout with strength endurance emphasis, targeting 20-minute oxidative energy system development. Primary challenge is maintaining pulling strength and core stability under accumulated fatigue while managing heavy dumbbell loading.

Coach Insight

Pace for 4-6 rounds total. Break pull-ups early - consider 3-3 or 4-2 from start to preserve grip and lat strength. On lunges, keep torso upright, step back to starting position between each rep for consistency. Transition quickly between movements but rest briefly before pull-up sets. Expect significant grip fatigue after round 3. Focus on controlled eccentric on pull-ups to save energy.

Benchmark Notes

This 20-minute AMRAP combines 6 weighted strict pull-ups (50/35 lb) with 100ft DB front-racked lunges (50/35 lb). Round analysis: Each round contains 6 strict pull-ups + 100ft lunges. Fresh times: Weighted strict pull-ups take 3-5 sec each (18-30 sec total), 100ft front-racked lunges take 45-75 sec. Total fresh round time: 63-105 sec. Fatigue analysis: Rounds 1-2 at base pace (75 sec avg), rounds 3-4 slow to 85 sec with grip fatigue from strict pull-ups, rounds 5-6 reach 95 sec as shoulders fatigue significantly, rounds 7+ become 110+ sec with frequent rest breaks. Strict pull-ups create severe cumulative fatigue - athletes will break into smaller sets (3-2-1, then singles) by round 4-5. Front-rack position becomes limiting after round 6 as core and shoulders tire. Transition time: 5-8 seconds between movements. Elite athletes complete 9-10+ rounds, average complete 5-6 rounds, beginners complete 2-3 rounds in the 20-minute window.

Modality Profile

Both movements are weighted exercises: Weighted Strict Pull-Up adds external load to a bodyweight movement making it weightlifting, and Dumbbell Front Racked Lunge uses dumbbells as external load. Two weightlifting movements = 100% W.
