When I stand with my feet flat and together, then lift myself onto my toes repeatedly. It's a pretty good calf workout, and I do about three reps of 100. Is there a name for this exercise/movement?	Yes, the exercise you're describing is commonly known as a "calf raise." Specifically, when performed with your feet flat and together, it's often referred to as a "standing calf raise." This exercise targets the gastrocnemius and soleus muscles in the calves and is effective for building strength and muscle endurance ...

I know this is a simple question, but it hasn't been asked on here yet (so it seems from my search results). What is the most nutrient-dense source of vitamin E?	The most nutrient-dense source of vitamin E is generally considered to be wheat germ oil. It is particularly high in alpha-tocopherol, which is the most active form of vitamin E in the body. Other excellent sources of vitamin E include sunflower seeds, almonds, hazelnuts, and spinach. Including a variety of these f...

Using the recumbent bike is a lot more comfortable but it also feels a lot more "lazy".	It's common to feel that way about recumbent bikes!

So I am on this 12 week transformation by Kris Gethin, and I am supposed to do 20mins of cardio twice a day, every day. So I'm thinking of alternatives of climbing stairs, running ,etc. So I thought - could sex be a form of cardio? Having sex for 20mins twice a day would be waaaay more pleasant and not as monotonous ...	Yes, sex can definitely be considered a form of cardiovascular exercise! Engaging in sexual activity can raise your heart rate and provide a good workout, as it involves physical exertion and can burn calories. The intensity and duration can vary, but 20 minutes of sex can be a fun and enjoyable way to incorporate card...

Chewing sugar-free gum, especially in moderation, is generally considered compatible with a paleo diet.
