Resistance training helps with weight management by building more muscle tissue, which burns more calories at rest than fat tissue. Resistance training also helps to maintain muscle mass that would otherwise be lost with age and inactivity. This makes it easier to perform many daily tasks (e.g. carrying groceries, snow shoveling, etc.) throughout life. In addition, resistance training helps to build strong bones and prevent osteoporosis.
The American College of Sports Medicine (ACSM) recommends performing
- at least one set (8-12 repetitions)
- of 8-10 exercises that work all the major muscle groups
- 2-3 days per week (You should not do resistance exercises for the same muscle groups on consecutive days.)
Free weights (e.g. dumbbells, barbells), machines, elastic bands, or one’s own body weight (e.g. push ups) can be used to create resistance. You should choose a form of resistance training you are comfortable using.
For the first 4 to 6 weeks of resistance training, chose weights or resistance levels that allow you to complete 12-15 repetitions of an exercise with minimal fatigue. During this time, your muscles will be adapting to resistance training; a lot of resistance is not necessary for these early adaptations to occur. Lifting too much too soon will make you quite sore, increasing the time you need for recovery between workouts and slowing your progress.
After 4 to 6 weeks, you can increase the level of resistance. Select a weight or resistance level at which you feel fatigue after 8-12 repetitions. If you cannot perform 8 repetitions of an exercise, the resistance is too great and should be decreased. If you can easily perform more than 12 repetitions, the resistance is probably not adequate and needs to be increased. Adequate resistance is necessary to enhance muscular fitness and improve body composition.
The following muscle groups should be targeted in any resistance training program:
- Chest (pectorals)
- Upper and middle back (trapezius and latissimus dorsi)
- Shoulders (deltoids)
- Front of arm (biceps)
- Back of arm (triceps)
- Back (erector spinae)
- Abdominals (rectus abdominus, obliques)
- Front of thigh (quadriceps)
- Back of thigh (hamstrings)
- Calves (gastronemius)
The following are examples of exercises that could be used to work the different muscle groups that should be targeted in a basic weight training program. These are just examples; there are many other exercises that can be used to work these same muscle groups. Video clips of how to properly perform exercises can be viewed on the following web site. (Click on the “exercise and muscle directory” link on the site’s home page.)
- Chest
- Push-ups OR
- Bench press with barbell or dumbbells
- Upper and middle back
- Bent-over dumbbell row - works trapezius, latissimus dorsi, rhomboids, rotator cuff muscles, and posterior deltoid
- Shoulders
- If you are only going to do one exercise for the shoulders, it is best to pick one that targets the middle (lateral) deltoid. Chest exercises also work the front (anterior) deltoid. Many exercises for the upper back also target the rear (posterior) deltoid.
- To work the lateral (middle) deltoid:
- Upright rows with barbell OR
- Lateral raises with dumbbells
- Overhead press with dumbbells or barbell OR
- Front raise with dumbbell or barbells
- Rear deltoid row with dumbbells OR
- Seated rear lateral raise with dumbbells
- Front of arm (bicep)
- Dumbbell or barbell curl
- Back of arm (triceps)
- Triceps extension with dumbbell or barbell OR
- Bench dips - This also works some shoulder, chest, and back muscles.
- Back
- Back extension (with or without added weight) - works the erector spinae and the hamstrings and gluteus maximus
- Abdominals
- Crunch (with or without weight or an incline) - works the middle abdominals (rectus abdominus)
- Twisting crunch (with or without weight or incline) - works the side abdominals (obliques)
- Front of thigh (quadriceps)
- Squats with dumbbells or barbells or sled OR
- Lunges with dumbbells or barbell OR
- Leg extension machine
- Back of thigh (hamstring)
- Standing leg curl with elastic band OR
- Seated or lying leg curl machine
- Calves (gastrocnemius)
- Standing calf raise with barbell OR
- Calf raise or calf press with sled
Again, there are many other exercises that work these muscle groups. Periodically changing the exercise you use to target muscle groups provides slightly different stimulus for your muscles and can enhance muscular fitness.

You many chose to add exercises to target additional muscles groups in order to personalize your workout. For example, working the shins (tibialis anterior) with reverse calf raises may helps to prevent shin splints in some runners.
