My dad's bought a new bike and has lost like 25 lbs over the past year...looking better than I can ever remember in over 20 years. My mom, who's a health nut, and I have been talking to him about adding some resistance training to his exercise routine (that's right, a mom who advocates strength training ). Anyway, he just joined the same gym as my mom, so he'll have access to absolutely everything you could need. Any advice I should give him? Obviously, at that age, he's not too concerned about getting huge, more just general wellness and strength as he ages. I thought compound lifts at medium weight for 6-10 reps/set. What should I tell him? If you guys know of any books that are out there on the subject that'd be perfect as I've yet to buy him a Christmas present Thanks guys!
