Write the next sentence in this paragraph:

How to get stronger
Challenge yourself with every workout.
When your aim is to gain strength, working out should never feel easy. In fact, that 30 minute to 1 hour period you spend lifting, pulling and pushing weight every day should be extremely uncomfortable.
If it's not, you aren't putting enough stress on your muscles to help them grow stronger. Challenge yourself to " go all in " with every single workout to see maximum results over time.
