Comprehensive training programs for individual sports are often “periodized." That is, they are broken into three or four phases over the year, with each phase concentrating on a particular fitness attribute.

For professional sports that utilize weights in their training—which is most these days, each phase has different objectives and each successive phase builds on the previous one.

A year-long baseball weight training program could look like the program outlined below. (Season cut-offs are based on the American baseball season.)

Baseball Workouts

Below you will learn about how and when to use the following exercises for your preseason, in season, and closed season baseball workouts:

Early preseason: January to February

  • Players are preparing for the season and starting to build up after the layoff.
  • Emphasis is on building foundational strength, muscle endurance, and size (hypertrophy).

Late preseason: March to April

  • Players are working up to the start of the season and pre-season trials are imminent.
  • Emphasis is on building maximum strength and power.

In-season: May to September

  • Competition is underway and players are expected to be fully functional for competition.
  • Maintenance of strength and power is emphasized.

Closed season: October to December

  • The season is over; time to relax for a while but you need to keep active.
  • Emphasis is on rest and recovery with maintenance of light activity—cross training, light gym work. Several weeks break from serious strength training is usually worthwhile. As pre-season approaches, more regular gym work can resume.

Sport- and Role-Specific Training

Within a generic training program for a sport, further specialty sub-programs and cycles may be useful, especially in teams where members have specific roles and certain advantageous physical attributes apply.

For example, a football quarterback and a defensive lineman will probably have a different program in the gym, one emphasizing speed and agility and the other bulk, strength, and power. A pitcher is likely to do different gym work than a designated hitter or a catcher.

Arm Is Everything

In baseball, your arm is everything, no matter what position you play. Training must be designed to strengthen and protect the throwing arm and shoulder at the same time.

A ballplayer with an injured arm is not useful to anyone, no matter how big and strong his biceps or shoulders are. The pitcher’s arm, of course, is worth millions of dollars at the highest levels of the game and needs to be treated as an asset.

Even if you are a budding young pitcher, taking good care of your arm with graded training and playing is an essential strategy for longevity.

A pitcher's strength training program may differ from that of a catcher. A catcher could place more emphasis on low squatting exercises for example, whereas a pitcher would emphasize arm endurance, power, and single-leg balance and torso rotation.

Pitchers need to work on strengthening the shoulder rotator cuff muscles to ensure freedom from painful and debilitating impingement injuries that can be long-lasting.

Hitters rely on bulk, strength, and power—and a good eye—to propel that ball over the fence. Sammy Sosa, Barry Bonds, and Mark McGwire are good examples, notwithstanding the controversies over possible supplement and steroid use. Yet they still need to be agile in the field, designated hitters aside. A missed "out" can easily negate the value of a hit.

Consider the program presented here to be an all-around program, best suited to beginners or casual weight trainers without a history of weight training for baseball. The best programs are always specific to an individual's current fitness, role in the team, access to resources, and, no less important, the team coaches' essential philosophy.

You will be best served by using the following program in conjunction with a trainer or coach.

If you're new to weight training, brush up on principles and practices with the beginner resources.

Always warm up and cool down before and after a training session. A medical clearance for exercise is always a good idea at the start of the season.

Phase 1 - Early Preseason

How this phase is approached will depend on whether a player is new to weight training or is coming off a season of weights. Building foundation strength means utilizing a program that works all the major muscle groups of the body. Less-experienced weight trainers will need to start with lighter weights and work up to heavier weights.

Repetitive sports activities can strengthen one side of the body at the expense of the other, or emphasize one or two major muscle groups with similar effect. Inevitably, weak areas can be susceptible to injury and can perform poorly.

This is not to say that your non-throwing arm has to be as good as your throwing arm, but it does mean that you need to allocate sufficient training resources so that you achieve functional foundation strength in all areas, including opposing muscles and left and right sides of all major muscle group areas including back, buttocks, legs, arms, shoulders, chest, and abdominals.

In the early preseason, the foundation program encompasses a mix of endurance, strength, and hypertrophy objectives, which means that the weights are not too heavy and the sets and repetitions are in the range 2 to 4 sets of 12 to 15 repetitions. In this phase, you build some strength, and some muscle size and endurance.

In pre-season, you should also start doing specific rotator cuff strengthening exercises or continue with these exercises if you have been doing them in the break.

The rotator cuff is a complex of muscles, ligaments, and tendons that control the shoulder ball and socket joint, which is susceptible to overuse and shock injury.

Duration: 4-8 weeks
Days per week: 2-3, with at least one rest day between sessions and a lighter week in week 4 to promote recovery and progression.​
Reps: 12-15
Sets: 2-4
Rest between sets: 30-60 seconds

Phase 1 Exercises

Rotator cuff arm/shoulder exercises for both arms

Duration: throughout pre-season and in-season.
Days per week: 3-4
Reps: 12-15
Load: light weight with minimal strain to completion of a set
Sets: 3
Rest between sets: 30 seconds

The rotator cuff exercises can be done with a cable machine, rubber bands, or tubes.

External rotation: Move the arm outward, away from the waist
Internal rotation: Move the arm across the body at the waist
Extension: Move the arm to the rear
Abduction: Move the arm upward away from the body

Points to Note

  • By trial and error, find a weight that represents a taxing lift for the last few reps of each set. If you're unsure, start with a light weight and increase it as you get stronger within the training period so that the perceived effort remains similar.
  • Don't lift too heavy in this phase. The last few reps in a set should be taxing yet without extreme effort to "failure", especially for the arm and shoulder exercises. You want the arm and shoulder prepared for work but not overtaxed. The rotator cuff strengthening exercises are deliberately lighter.
  • Do front squats or dumbbell or sled hack squats if the rotation required to position a barbell on the shoulders for the traditional back squat stresses the shoulder joint to the point of discomfort.
  • Shoulder joint protection is important at this and subsequent stages. This message will be repeated throughout this program.
  • Circuit training, running training, and plyometrics such as bounds and jumps can be added to this gym program as well, resources, and time permitting.
  • Stop immediately if acute pain is noticed during or after an exercise, and seek medical and training advice if it persists.

Phase 2 - Mid-Preseason

Strength and Hypertrophy Phase

In this phase, you will build strength and muscle. You have a good foundation from early pre-season workouts, and now the emphasis is on lifting heavier weights in order to train the nervous system in conjunction with the muscle fibers to move bigger loads.

Hypertrophy, which is building muscle size, does not necessarily imply strength, although in the foundation phase and in this phase hypertrophy will serve you well for strength development.

Strength will be the foundation for the next phase, which is power development. Power is the ability to move the heaviest loads in the shortest time. Power is essentially a product of strength and speed.

Time of year: Mid-pre-season
Duration: 6 weeks
Days per week: 2-3, with at least one day between sessions
Reps: 4-6
Sets: 3-5
Rest in between sets: 2-3 minutes

Phase 2 Exercises

  • Barbell squat or sled hack squat
  • Incline dumbbell bench press
  • Romanian deadlift
  • Lat pulldown to front with wide grip
  • Pull ups - 3x6 - add weights if you find this too easy, or just go to "failure" if it's too much.

Continue with rotator cuff strengthening as in the first phase.

Points to Note

  • Adjust the weight so that the final few repetitions are taxing but not to failure. The fewer reps mean that you will be lifting heavier in this phase.
  • Don't lift to failure for the upper body exercises such as the dumbbell press and lat pull down and hold good form. Keep the forearms in a vertical plane with the upper arms not extending excessively below parallel.
  • If you are unable to recover from a session with only one rest day in between, re-schedule this program to two sessions each week rather than three. Strength training can be very physically and mentally demanding.
  • You will be sore in the muscles after these sessions. Muscle soreness or delayed onset muscle soreness (DOMS) is normal; joint pain is not. Be sure to monitor your arm and shoulder reactions to this phase. Back off when any joint pain or discomfort is felt.

Phase 3 - Late Preseason

In this phase, you build on the strength developed in phase 2 with training that will increase your ability to move a load at high velocity. Power combines strength and speed. Power training requires that you lift lighter weights than you did in the strength phase, yet with explosive intent.

You need to rest adequately between repetitions and sets so that each movement is done as fast as possible. The number of sets can be less. There is no point to training like this when you're fatigued.

Time of year: late pre-season
Duration: 4-6 weeks
Days per week: 2-3
Reps: 8-10
Sets: 2-3
Rest between repetitions: 10-15 seconds
Rest between sets: at least 1 minute or until recovery

Phase 3 Exercises

  • Barbell or dumbbell hang clean
  • Cable wood chop
  • Cable push-pull
  • One arm cable raises each arm
  • Medicine ball or dumbbell push press
  • Medicine ball standing twist with partner (6x15 fast, recover between sets) (or alone)
  • Box jump march (6x20 fast, recover between sets)
  • Vertical jump

Continue with rotator cuff exercises as in phase 1.

Points to Note

  • It's important that you are relatively recovered for each repetition so that you can maximize the velocity of the movement. The weights should not be too heavy and the rest periods sufficient.
  • At the same time, you need to push or pull reasonably heavy loads to develop power against reasonable resistance. Lift heavier than phase 1 but lighter than phase 2. This should be approximately in the range 50-70% of your 1RM (maximum lift) depending on the exercise.
  • With the marches and the medicine ball twists, do a full set at maximum and then rest sufficiently before the next one.
  • Rest briefly between each vertical jump so that you can maximize each one.

Phase 4 - In-season

Maintenance of Strength and Power

Alternate phase 2 (Strength) and phase 3 (Power) for a total of two sessions each week. Every fifth week, do no weight training at all to assist recovery.

Continue with the rotator cuff exercises until the end of the playing season.

Points to Note

  • Try to allow at least two days between any strength session and a game.
  • Try not to do strength training on the same day as you work out on the diamond.
  • Rest completely from strength training one week in five. Light gym work is fine.
  • Use your judgment. Don't sacrifice skills training for weight work during the season.

Phase 5 - Off-season

Now it's time to rest up. You need this time for emotional and physical renewal. For several weeks you should forget about baseball and do other things. Staying fit and active with cross-training or other activities is still a good idea. By mid-November, you may want to think about some light gym work, rotator cuff exercises, and aerobic work.

Wouldn't you know it—it's nearly time to do it all again.
