Workout Description

Why This Workout Is Medium

Pull-ups are the limiting factor, but the complementary pairing with box step-ups (lower body) allows partial grip and lat recovery between movements. The 45/35 lb step-ups are light enough to avoid meaningful leg interference with pulling. Two 10-minute AMRAPs with 4 minutes rest creates real cumulative pull-up volume, but the structured rest mid-workout prevents total grip failure. Average athletes will break pull-ups into sets but can sustain work throughout.

Training Focus

This workout develops the following fitness attributes:

• Stamina (8/10): Accumulated pull-up and weighted step-up volume across 20 total minutes of work challenges upper body pulling and lower body muscular endurance significantly. Grip and leg fatigue will compound.
• Endurance (7/10): Two 10-minute AMRAPs with minimal rest drives sustained cardiovascular output. The aerobic system is heavily taxed across both intervals, making this a strong aerobic capacity test.
• Speed (4/10): Efficient transitions between movements and consistent rep pacing matter across both AMRAPs. Sprint-cycling is counterproductive; smart, repeatable pacing dominates the strategy here.
• Strength (2/10): Pull-ups are relative bodyweight strength and step-ups use moderate loads (45/35). Neither movement demands near-maximal force production; this is endurance-focused rather than strength-focused.
• Flexibility (2/10): Basic hip flexion for box step-ups and shoulder/lat range for pull-ups required. No extreme mobility demands. Standard functional range of motion is sufficient throughout both intervals.
• Power (2/10): Steady AMRAP pacing discourages explosive cycling. Step-ups are controlled and deliberate. Kipping pull-ups offer minor power expression, but sustained output is prioritized over explosiveness.

Movements

• Pull-Up
• Box Step-Up

Scaling Options

For pull-ups: reduce to banded pull-ups, ring rows, or jumping pull-ups depending on ability. Athletes with 3-5 strict pull-ups can use a light band. For box step-ups: reduce the load to 25/15 lbs or bodyweight only if needed. Step-up box height can also be lowered from standard 20 inches to 12-16 inches if knee discomfort or balance is an issue. Volume modification: reduce pull-ups to 6-8 reps per round if grip or upper body fatigue is a limiting factor disproportionate to fitness level. Rep scheme can be 6 pull-ups and 10 step-ups for newer athletes to keep movement quality intact throughout the full AMRAP.

Scaling Explanation

Scale pull-ups if you cannot perform at least 5 unbroken pull-ups when fresh — struggling athletes will spend too much time hanging and lose the intended conditioning stimulus. Scale the load on step-ups if you cannot maintain a controlled, upright posture for the majority of the AMRAP. The priority here is intensity through consistency — you should be moving for the vast majority of each 10-minute window with only brief, planned rest. If an athlete is stopping for more than 15-20 seconds between movements regularly, the weight or volume is too high. The target is 6-10 rounds per AMRAP at Rx, and scaling should put all athletes in that range to preserve the aerobic stimulus.

Intended Stimulus

This is a moderate time domain effort — two sustained 10-minute pushes with built-in recovery. The goal is consistent, repeatable output across both AMRAPs, targeting aerobic capacity and muscular endurance. Expect a hard, steady engine effort rather than an all-out sprint. The primary challenge is managing grip fatigue from pull-ups while maintaining a strong, controlled pace on step-ups. The 4-minute rest window should allow enough recovery to match or come close to your round count in the second AMRAP — if you fall off dramatically, you went too hard in round one.

Coach Insight

The key to this workout is disciplined pacing from the first minute. Do not sprint out of the gate on pull-ups — break them into manageable sets early, such as 5-5 or 6-4, even if you feel fresh. Grip fatigue accumulates fast and will catch up with you by minutes 6-8. On box step-ups, keep a tall chest, drive through the heel of the working leg, and control your breathing — these should be your active recovery movement between pull-up sets. Avoid locking out your knees aggressively at the top to protect joints under load. A common mistake is treating this like a sprint AMRAP and blowing up by minute 5 — instead, find a rhythm you can sustain for the full 10 minutes. Use the transition from step-ups back to the pull-up bar intentionally — take 3-5 controlled breaths before your next set. Aim for a consistent round pace throughout and use the rest period to shake out your hands and lower your heart rate before the second AMRAP.

Benchmark Notes

Primary limiters are pull-up capacity and grip, with weighted step-ups compounding fatigue each round. The 45/35 lb step-ups (loaded carry or vest/dumbbells) are moderately demanding but rarely the true bottleneck — pull-ups are. Score is total rounds across both 10-minute windows combined. L1 athletes are likely doing ring rows or jumping pull-ups with no additional load on step-ups, netting roughly 3 rounds per AMRAP. L5 intermediates can sustain about 7 rounds per AMRAP using 5+5 or 7+3 pull-up splits and a steady step-up pace (~80-90 sec/round), totaling ~14. L10 athletes maintain unbroken pull-ups for most sets and push step-up pace to sub-65 sec/round, hitting 12 rounds per AMRAP for ~24 total. The 4-minute rest between AMRAPs allows meaningful recovery, so L7+ athletes should post near-identical round counts in both windows, while L1-L3 athletes will see a noticeable drop in round 2 due to grip and upper-body fatigue. Female targets are one round lower at most levels due to slightly reduced pull-up capacity on average; the load difference (35 vs 45 lb) on step-ups is secondary.

Modality Profile

Pull-Up is a gymnastics movement (bodyweight). Box Step-Up is a weightlifting movement (external load/weighted bodyweight movement). 2 movements total: 1 gymnastics, 1 weightlifting = 50/50 split.
