Question: I need to lose a considerable amount of weight and am suffering from information overload. Should I be focusing more on cardio than strength at this time since I have nearly 100 pounds to lose?
Ideally I would go 50% cardio and 50% toning/strength for the following reasons.
When it comes to burning calories cardio exercise has a slight advantage. You'll burn 8 to 10 calories a minute doing toning/strength exercises with weights compared with 10 to 12 calories a minute doing cardio exercises.
On the other hand, strength training gives you a metabolic boost that lasts several hours after your workout because your body will work overtime helping your muscles recover. That means you'll continue burning calories for hours after the workout is done! With cardio workouts the 'after workout effect' is much less.
To give you the best results I would split my workouts between both as In my opinion both are equally important for your overall fitness level and in helping you lose the extra weight. Remember, Cardio exercise is essential in maintaining a strong heart, lungs and blood flow. Toning/strength exercise is an excellent metabolism booster.
