Week 25 - Get Strong
The challenge: Do 20 to 30 minutes of strength training three days per week.
It suggests taking a class or using books or DVDs. You can do exercises such as weight training, circuit/interval training, body-weight exercises, resistance training, isometrics, or plyometrics.
Does anyone have any ideas? I was thinking of looking on Youtube for some dumbbell workouts. I'd love to hear some recommendations.
