Weekly Health Challenge: Push Ups And Weight Lifting

As you can see, I've added the Weekly Challenge Level Two, finally. It's still in the developmental stage (which means it's not finished yet and I'm still working out the kinks) but it's here. I've also added the 'extra challenge,' which is part of Level Two. If you have any suggestions please leave them in the comments below! :)
Weekly Challenge (Level One): Lift weights three days a week

Weight training is important, especially for women. By lifting weights you can increase your bone mass, and therefore decrease your risk of breakage later. And don't worry about bulking up if you're a woman - women typically build lean muscle, or find it difficult to build up large muscles like men can.

If you don't have weights, bags of books can be used instead, or even cans of food. You can do simple biceps curls, or one of these.

Here are some tips! Remember to stay safe; incorrect weight lifting can hurt you.
Weekly Challenge (Level Two): Pushups: Five each day, for five days this week

There are so many ways to do these wrong it's ridiculous (for info on proper technique, you can look here). If you have a problem doing them on your toes, try this, instead of on your knees. I know it looks a little silly, but it'll help.

Make sure you push yourself, too. Not so hard you can't lift your arms over your head the next day, but enough to get good work on your arms. Extra Challenge!
Is Level Two too easy? Double the pushups!
