The answer is: It depends. (NOT AGAIN?)
Physiologically speaking, men tend to store more visceral (internal organs) fats while women tend to store fats around their hips and thighs. This means that men should be doing more cardiovascular activities to reduce risks of heart attacks and strokes.
Women, on the other hand, should consider strength training to reduce the risk of osteoporosis.
While men tend to dominate the weights corner of the gym more often than women, there is nothing wrong with it. If you are struggling with fat loss despite running for long distances, then perhaps it is time to consider increasing the frequency of strength training.
Truth: High volume of cardiovascular activity without ample recovery time will impede fat loss. Now back to our initial topic: you may adopt cardiovascular activities with 2 points in mind.
1. current training age
How long you have been training will affect the rate of progress. If you have been training for a long while, your body would have adapted to the current stress load that you have been giving it. This applies also to females who have been performing strength training for a period.
2. plateau
For someone who has been consistently training and eating well, adding cardiovascular activities will assist you with the extra percentage fat drop when you have reached a plateau.
Cardio activities need not have to come in the form of running, think:
- Inclined treadmill walking
- Long distance outdoor walking
- Skating
- Cycling
- Long distance swimming
Basically, choose movements that are gentle on the joints in the long term. If you are a beginner, you would most probably lose body fats and weight the moment you start adjusting food and increase exercise level.
For the advanced, you could consider point 2.
