FACTOID: muscle burns fat and raises your heartrate FAST. Based on that, the fastest way to fat loss via exercise is a 4-minute high-intensity muscle-engaging workout! 4 minutes? I'm in. The mantra "use it or lose it" applies quite specifically to muscles over the age of 30. Yes, 30. Over the age of 50, well, the downhill slide is faster than anyone ever dreamed possible.
I’d like to see your 12 min workout on video
I will do that! Just finished todays workout.
