Ed Warren, who died last Wednesday at his Monroe, Conn., home at 79, was a self-described and self-trained demonologist whose tangles with the supernatural took him from The Amityville Horror to the Loch Ness monster.

How often can you train with a low intensity/high rep approach? A toning style core routine can be performed 4-6 days per week once you have built up your tolerance for those exercises, but if you become overly sore you may need to take a 48 hour break to allow muscles to properly heal. Just make sure you take at least one day off each week, even if you never get sore.
