My mom, who is in great shape, is 63, 5'3" and ~ 135 lbs. She's actually an inspiration in that she weight trains and eats right, and has done so for most of her adult life. She tends to accumulate fat around her midsection, and while she knows she can't spot reduce, she would like to reduce the fat in this area (she knows this will involve losing fat all over to begin with). Right now, she weight trains 2 to 3 times a week and does cardio at about the same frequency for about 30 min. She eats a clean 1600 to 2000 calories daily. I've seen her do cardio and it looks to be at a pretty moderate pace (she says her HR never goes above 125). I've suggested she do it a little more intensively, but she heard on the radio some doctor say that people over 60 should not exercise at higher than 75% of their MaxHR, which in her case would be 122 bpm. Firstly, does anyone know if there's any validity to the statement that people over 60 should not exercise at higher than 75% of their MaxHR? Secondly, what would you recommend for fatloss? Longer cardio sessions? More frequend cardio sessions? She says she gets bored doing cardio (loves the weights though!), but it seems to me this is the only way to go, while maintaining her current calorie intake.
