Squats! Leg Presses!
My wife is a competitor, and, of course, all her friends want to look like her, but they are soon asking if they cannot substitute this or that for squats or leg presses, or this or that fluffy carb food for protein, LOL! Squats and leg presses are hard, especially once a female finds out she does indeed have the strength in her legs to press with "the big plates" on each side.
Her friend she has been trying to help, can't figure out how to eat 150 grams of protein, even after my wife laid out an entire day of meals for her . . . and she wanted to know what kind of cereal to eat for breakfast. "You did not see the Quaker Old Fashioned Oats?" LOL! She meant like Lucky Charms or Honey Nut Cheerios . . .
