The published table, 20s through 60s
Here is the Canadian push-up table as reproduced in the CSEP Physical Activity Training for Health resource manual (2019) and in the American Council on Exercise's assessment sheet, which cites it. The 40s, 50s and 60s are the focus. The 20s and 30s are included so the shape of the change across decades is visible. Men's counts are toe push-ups. Women's counts are knee push-ups.
The table stops at 69. There is no published row for 70 and older in this dataset, so any chart that extends it has borrowed or estimated those numbers from somewhere else.
What the decade pattern shows
A few patterns stand out once the rows sit side by side. Counts fall with every decade for both sexes. The drop is steep between the 20s and 40s and flatter after that. For men, the entry point to "Excellent" goes from 36 in the 20s to 25 in the 40s and 18 in the 60s. The "Good" band for men in their 50s spans just three reps, from 10 to 12. That's narrow enough that a single rep can move a count across a label.
The women's column tells a slightly different story. By the 50s, "Excellent" (21 or more) sits at the same number as the men's, but it's measuring knee push-ups against toe push-ups, so the two rows can't be read as equal performance. In the 60s, the women's "Good" band (5 to 11) is wider than the "Very good" band above it. That's reproduced exactly as published and reflects how the original categories were cut, not a typo here.
Daily Vitality's Walking Speed by Age guide shows a similar decade-by-decade shape for a very different kind of measurement.
