What’s the Best Exercise?
“Is there a single activity that has proved to be, at once, more strenuous than walking while building power like the squat? High-intensity interval training, or H.I.T. as it’s familiarly known among physiologists, is essentially all-interval exercise. As studied in Gibala’s lab, it involves grunting through a series of short, strenuous intervals on specialized stationary bicycles, known as Wingate ergometers.
Sun Rays
Human skin has special cells, melanocytes. These cells provide natural, built-in sun protection. You can see it in action each time you tan. Melanocytes produce dark brown substance, called melanin, which does not allow sun rays to penetrate deep into the skin layers as it would be damaging. At the same time sun light stimulates cell generation, skin becomes thicker, and therefore more resistant to UV rays. Turns out the sun is actually good for the skin.

Rebounding
Rebounding is a unique exercise in that you achieve a weightless state at the top of each jump then land with twice the force of gravity on each bounce. This twice-gravity bounce affects every muscle and cell of the body. Researchers at the University of Kentucky, in conjunction with NASA, concluded that “the magnitude of the biomechanical stimuli is greater with jumping on a trampoline than with running.”
NASA did research back in the late 70s and 80s, and it discovered that astronauts, after some time in space, would lose close to 14-15% of bone mass. One way the scientists believed that astronauts could get the appropriate strength conditioning to counteract this loss was from rebound exercise. Their research indicated that rebounding was 68% less traumatic to the musculoskeletal system than jogging on a hardwood surface or cement surface. So, their study really gave credibility to rebound exercise as a non-jarring exercise and as something that could maintain the strength of the bones.
