4 mins using the Tabata method, everyday, is much more significant than a steady 30-60 minutes jog/walk, 5 days a week.
A study shows that a steady state training (ex: walking, jogging..) is only beneficial for increasing your Aerobic capacity. However, Tabata protocol is the way to go if you wanted to benefit to increasing , both human energy systems, Aerobic and Anaerobic capacity.
Tabata workout is an interval type of workout. It consists of (20 seconds reps + 10 seconds break) * 8 sets = 4 minutes of a condensed workout. it can include any type of workouts like the examples showed:
Squats
Burpees

Does snow = Fat ?
Him: Buddy !

I: What ??
Do you know that you can melt away the fat just through perspiration (sweating) ?
No, that's not true !
Yes it is, its like the snow piled up on your front yard, it melts away in a shape of water when the temperature rises. Or when you put liquid oil/fat in the freezer, it becomes solid in a shape of cream/lotion doesn't it ??! (hint: Vaseline )
Yes, but humans bodies are different. According to live strong.com, 5 calories are burned for every 1 liter of Oxygen consumed. Meanwhile, perspiration's purpose is to cleanse and cool down the body, and the only weight that we lose during that process is water weight!
