American College of Sports Medicine and American Heart Association updated their physical activity guidelines.
It is highly suggested that you strength-train at least twice a week and work out all of the major muscle groups on top of a regular cardio work out.
Both these groups recommend that adults perform eight to 12 reps of eight to 10 exercises -- lower legs, upper legs, arms, shoulders, chest, back and arms. Use free weights, machines or weight-bearing activities.
No matter how old your body is, these experts say a crucial part of strength training is working in movements that involve the whole body.
Do we really need to workout with weights? Is a machine any better at working our chest and arms than a good old-fashioned push up? I say if you feel it the next day, it was weight bearing. Any other thoughts on this? I feel like yoga and pliates are weight bearing - but it's your own body weight you work with.
