Workout Description

Why This Workout Is Hard

While individual elements are moderate (50/35lb DBs, basic movements), the 20-minute continuous AMRAP creates significant cumulative fatigue. Weighted strict pull-ups will quickly compromise grip strength, then immediately carrying heavy dumbbells in front rack position taxes the same grip and adds shoulder/core demand. The constant work with no built-in rest means fatigue accumulation throughout, making this substantially harder than the weights alone suggest.

Training Focus

This workout develops the following fitness attributes:

• Stamina (8/10): High-volume strict pull-ups and extended lunging will severely test upper body pulling stamina and leg muscular endurance over the duration.
• Endurance (7/10): Twenty minutes of continuous work with weighted movements creates significant cardiovascular demand, requiring sustained aerobic capacity throughout the AMRAP format.
• Strength (6/10): Weighted strict pull-ups with 50/35lb dumbbells and front-racked lunges demand considerable absolute strength, especially as fatigue accumulates.
• Flexibility (4/10): Front rack position requires good shoulder and wrist mobility, while lunges demand hip flexor and ankle flexibility for proper mechanics.
• Speed (4/10): Pacing becomes critical to maintain consistent round times, but the strict nature of movements limits overall cycling speed potential.
• Power (2/10): Strict pull-ups eliminate kipping momentum and lunges are controlled movements, making this primarily a strength-endurance challenge rather than explosive.

Movements

• Front Rack Lunge
• Weighted Strict Pull-Up

Scaling Options

Reduce DB weight to 35/25 or 25/15 lbs. Substitute banded strict pull-ups or bent-over DB rows. Reduce lunges to 75ft or 50ft. Consider bodyweight strict pull-ups if athlete can do 8+ unbroken.

Scaling Explanation

Scale if athlete cannot perform 3+ weighted strict pull-ups at Rx weight or cannot maintain front rack position for 50+ steps. Goal is 4-6 complete rounds with consistent movement quality. Prioritize maintaining stimulus over hitting Rx weights - better to move consistently than rest excessively between sets.

Intended Stimulus

Moderate aerobic capacity workout lasting 20 minutes focusing on oxidative energy system. Primary challenge combines upper body strength endurance with lower body muscular endurance while carrying load. Tests ability to maintain consistent pace under accumulated fatigue.

Coach Insight

Pace conservatively for first 3-4 rounds to establish rhythm. Break weighted pull-ups into 3-2-1 or 2-2-2 early to avoid failure. Keep DBs in front rack position throughout lunges - resist urge to rest them. Take 30-45 seconds between movements for grip recovery. Count lunge steps carefully (50 steps each leg). Expect significant grip fatigue after round 6-8.

Benchmark Notes

This 20-minute AMRAP combines weighted strict pull-ups with front-racked lunges. Round 1 analysis: 6 weighted strict pull-ups take 12-18 seconds (2-3 sec per rep), plus 100ft DB front-racked lunges (50 steps at 2-3 sec each) = 100-150 seconds, plus 10-15 seconds transition = 125-180 seconds total. Round 2: Fatigue increases pull-up time by 20% (14-22 sec) and lunge time by 15% (115-175 sec) = 145-210 seconds. Round 3: Pull-ups become 30% slower (16-24 sec), lunges 25% slower (125-190 sec) = 155-230 seconds. By Round 4: Pull-ups may require set breaks (2+2+2 with 5-10 sec rest), lunges require more frequent breaks = 180-260 seconds. Weighted strict pull-ups are extremely demanding and will be the limiting factor. Most athletes will hit failure on pull-ups by rounds 3-4. Elite athletes (L9-L10) can maintain larger sets longer and complete 6+ rounds. Advanced athletes (L7-L8) manage 5-6 rounds with strategic breaking. Intermediate athletes (L4-L6) complete 3-4 rounds before significant breakdown. Beginners (L1-L3) may only complete 2-3 rounds, potentially needing to reduce weight or use bands.

Modality Profile

Both Weighted Strict Pull-Up and Dumbbell Front Rack Lunge are weightlifting movements using external load, making this 100% weightlifting modality.
