What is the calculated 1RM result for a 60 kg load performed for 3 reps using the specified formula?

Explanation:
Estimating a one-repetition maximum from a submaximal set uses a simple linear scale that increases the weight a bit for each additional rep. Using the O’Conner formula, 1RM = weight × (1 + reps × 0.033). For 60 kg done for 3 reps, the multiplier is 1 + 3 × 0.033 = 1.099. Multiplying by 60 kg gives 60 × 1.099 ≈ 65.94 kg. So the calculated 1RM is about 65.94 kg. Small rounding differences in the constant (0.033 vs 0.0333) can shift the final value slightly, but this is the intended result for this formula.
