Stack of Cheese
Five duos remained heading into Episode 4, and for the second consecutive week Redline arrived carrying an immunity advantage — this time earned outright in Episode 3 rather than inherited. The challenge was the most aggressively physical of the season so far, built around overhead pressing and partner-load coordination in a format that producer notes later described as "the one that separates the people who trained together from the people who just showed up together." Grindstone — the most unlikely surviving team through the first three episodes — ran out of road in the fourth.
Redline's Immunity
Redline entered Episode 4 with the immunity earned in Episode 3's hidden clause. Their E3 finish of 3rd — despite being protected — gave them no weekly winner advantage to carry forward. They competed in Episode 4 in full, but their result carried no elimination consequence regardless of where they placed.
Two consecutive weeks of immunity — Episode 3 via the hidden clean-hold clause, Episode 4 via that same earned protection carrying forward — made Redline the first duo in BOND history to survive back-to-back episodes without elimination risk. Cole Brandt later said in post-season interviews that they "didn't really think about it until it was over."
The Challenge
"Stack of Cheese" was a two-stage overhead pressing relay. In Stage 1, one partner stood beneath a suspended barbell loaded to 60% of their stated bodyweight and pressed it to lockout as many times as possible in 90 seconds. Every successful rep added one foam block — a "cheese" — to a platform beside them. In Stage 2, the other partner had 90 seconds to press a barbell loaded to their own 60% bodyweight for reps, with their rep count multiplied by the number of blocks stacked by their partner in Stage 1.
The mechanic meant Stage 1 performance directly amplified Stage 2 output — a weak Stage 1 not only reduced the raw block count but mathematically compressed every rep their partner could earn in Stage 2. A duo where one partner dramatically outperformed the other in Stage 1 could still be undone if Stage 2 didn't hold. Total score was Stage 1 blocks multiplied by Stage 2 reps.
Role assignment was again determined by producers before the episode. Neither partner knew which stage they would run until the morning of filming.
What Happened
Grindstone's issue was not lack of effort. Omar Saleh ran Stage 1 and posted 14 reps — the third-highest Stage 1 count of the episode — giving Vic Huang a solid platform to build from. But Vic's Stage 2 performance, pressed at his own bodyweight percentage, produced only 9 reps under the 90-second clock. The multiplicative scoring system meant 14 blocks times 9 reps equaled 126 — workable against a weaker field, fatal against a field of five.
Lockstep's Adrienne Coles posted 17 Stage 1 reps and Simone Hartley answered with 14 in Stage 2 for a total of 238. Ironblood and Bloodline both cleared 180. Even Redline — competing under immunity with no strategic pressure — posted 156. Grindstone's 126 was last by 30 points.
The multiplier trap: Grindstone had survived three prior episodes by finishing narrowly above last. In Episode 4 the multiplicative format meant there was nowhere to hide a gap between partners. The 14-block platform Vic Huang received was generous. The 9-rep Stage 2 was not.

Trivia
Ironblood and Bloodline finished tied at 180 points — the first tied result in the show's history. Under the tiebreaker rules, the duo with the higher Stage 2 rep count was ranked higher, giving Bloodline 3rd and Ironblood 2nd. The tiebreaker clause had never been publicly announced; its appearance in Episode 4 prompted ABC to include it in the official rules graphic aired before Episode 5.
Lockstep's second weekly win in three episodes put Adrienne Coles and Simone Hartley ahead of every other team in advantage accumulation. Their win in Episode 4 gave them the right to set the Stage 1 order in a future challenge — an advantage they banked rather than used immediately.
The "Stack of Cheese" title was reportedly a production nickname for the foam blocks used in the challenge — a reference to their resemblance to deli slices — that stuck during development and was never replaced with a more formal title before filming.
Vic Huang's 9-rep Stage 2 performance was not the lowest individual rep count of the episode — one competitor posted 8 — but the multiplicative structure meant the surrounding context mattered more than the raw number. In a different pairing his score would have been survivable.
Grindstone's three-episode survival run — 6th, 6th, 5th — made them the team most consistently near the elimination line without going over it prior to their exit. No team in Season 1 spent more episodes in the bottom two positions before being eliminated.
Omar Saleh's send-off included the line: "We weren't supposed to make it this far. We knew that." It was not delivered with regret. Vic Huang nodded once and said nothing. The two shook hands before leaving the arena, which was the only send-off handshake of Season 1.
