Should I use light resistance and complete high repetitions?
or
Should I use heavy weights and low repetitions?
This question can be controversial and will likely spark up a debate within the fitness industry and amongst professionals. The answer will differ depending on one's own personal preference and who you consult on the topic. A conventional personal trainer will most likely promote heavy resistance paired with low repetitions. Whereas, other methods like martial arts, yoga, and Pilates tend to favor lighter resistance (if any) and high repetitions. To obtain the best results, make sure to always focus on the quality and form in which the movement is performed. Working out in poor alignment in hopes of lifting more or doing more will only result in injury.
Using a light resistance and doing more repetitions will train the fast twitch muscles and build your strength endurance. This can create a more aerobic type of calorie burn, and is more beneficial on your joints. It will create long lean lines in your muscle development. Most women do not like the 'bulky muscle feeling' they get from heavy weight lifting and will tend to favor this type of workout. If you tend to bulk easily, using light weight (between 3-8 lbs) and lots or repetitions (more than 20 reps) is best for you. Another good rule of thumb is to complete as many repetitions as you can with very good form. Keep in mind- It is all about the quality of your movement, not the quantity. This is why Pilates is such a great choice because it replaces weights with spring resistance technology which creates a lengthening or stretching within the muscle fibers. Many methods like Martial Arts, Yoga, or the Pilates Mat work use your own body to create the resistance.
When you use heavy resistance, you are working the larger muscle groups. Heavy weight training will result in gaining strength rather than creating muscular endurance. If your goal is to increase the size of and build up your muscular structure, then opt for a heavier resistance with low repetitions. This is a favorite among body builders, cross-fit and many boot camp driven methods. Choose a weight that is heavy enough in resistance so you can only complete 10-12 repetitions with excellent form. Again, the quality of the movement and maintaining good form is still a key factor to prevent injury and to correctly complete the work. This is an excellent way to burn more calories efficiently and boost your metabolism when done before your cardiovascular exercise.
High reps (more than 20) plus low weight = fast twitch muscle fiber or endurance and toning
Low reps (between 10-12) plus heavy weight = slow twitch large muscle groups or strength gaining/building
Bottom Line: both are beneficial, it comes down to personal choice and what you are trying to achieve with your own body. Try both methods and see which one feels right for you. You can always do both within the week. Switch up your method throughout the week and use heavier resistance one day with low reps, and lighter weights the next with many repetitions. This way you will train the large muscles along with the smaller fast twitch muscles to compliment strength with endurance.
Don't forget to pair resistance training with 3-6 days of a cardiovascular workout. You have to burn the fat to even see the toning and the muscle definition results. Also keep in mind, the more muscle you build, the more efficiently your body will burn off fat during cardiovascular exercise and while at rest.
*As with any new fitness program, consult your physician and work closely with a certified trainer. Always listen to your body and if you feel pain during any exercise, stop or modify.
