Getting our required physical activity that gets us sweaty and does what it can to clear out the sludge in our arteries really can be handled in about a 10 minute spurt of intense exercise ie: quick paced walk or run or bike ride or just taking the stairs UP somewhere or resistance training! That is the latest: take several 10 min brisk moving of your choice workout several times a day then 4-5 days per week. Keeping it do-able and EASY! And do what you LOVE doing especially if it is OUTSIDE!
