In the Zone block calculation example, what activity level (as a decimal) was used to determine daily protein?

• A. 0.7
• B. 1.0
• C. 0.9
• D. 0.8

Answer: (C)

The idea here is that protein targets are scaled by how active you are, using a decimal multiplier to match training demand. In the Zone block calculation example, the activity level chosen was 0.9, reflecting a fairly high activity level. This multiplier increases your daily protein target compared with a lower activity scenario. The calculation uses body weight in pounds times 0.9 to get daily protein grams, and then you convert that into blocks (since each protein block equals 7 g). For example, a 150 lb person would aim for about 135 g of protein per day (150 × 0.9), which is roughly 19 blocks (135 ÷ 7 ≈ 19). The reason 0.9 is used here is to match the higher activity context described in the example; lower activity multipliers would yield smaller protein targets, while a multiplier of 1.0 would set the upper end for highly active scenarios.
