To find the percentage of Yael's workout that was spent lifting weights, you first need to calculate the total time she spent lifting weights.

Yael's total workout time was 2 hours, which is equivalent to 120 minutes.

She spent 21 minutes stretching and 45 minutes jogging, so the remaining time she spent lifting weights is:

Total time - (Stretching time + Jogging time)
120 minutes - (21 minutes + 45 minutes)
120 minutes - 66 minutes
54 minutes

Therefore, Yael spent 54 minutes lifting weights during her workout.

To find the percentage, divide the time spent lifting weights by the total workout time and multiply it by 100:

(54 minutes / 120 minutes) * 100 = 45%

So, 45% of Yael's workout was spent lifting weights.
