Rotational power training: the foundation for all athletic power
Jason Krantz explains how to improve your total body power and sport performance with rotational power training
All athletic movements involve a rotational component, either creating twisting movements through concentric muscular contractions (baseball swing, shot put) or resisting rotational movements/stabilizing the torso through isometric contractions. The ability to concurrently generate and transfer power in the torso originates from the core. The core includes the muscles of the abdominals, lower back, pelvic floor and hips. In the simplest terms: rotational training = core training = total body power training.
Below are some examples of how enhanced rotational strength and power improves total body power and athletic performance in different types of sports.
1. Straight line sprinting
Greater mechanical efficiency and better power transfer from arms/core to legs and ground due to a stable torso. The end result: faster times and longer jumps.
2. Change of direction sports (soccer, football, basketball, etc)
Greater lateral agility and change of direction ability along with greatly improved acceleration and better body control in the air. The end result: getting that one step jump on the opponent which is most often the difference between winning and losing.
3. Stationary sports (golf, baseball swing)
Increased hitting power. The end result is hitting the ball harder and farther. It should be noted that excellent agility is a critical trait in most sports, such as football, soccer, basketball and tennis. Discussing the training of agility is beyond the scope of this article, but a solid core serves as a great foundation from which agility can be improved from.
How we develop rotational sport specific power
It is usually assumed that strength training is the best way to increase both general and sport specific power. The idea is that any incremental strength gains in the weight room will transfer directly and completely to the athletic playing field. Classic Olympic style lifts, such as the squat, power clean and snatch are great movements for developing general, total body linear strength and power. However, these lifts in no way replicate the way power is developed in most athletic movements (Shepherd 2004; Siff et al. 1998)[1,2]. I remember a conversation with my track coach during my freshman year of college. I asked him why we did not spend more time in the weight room doing heavy squats and other "traditional" conditioning exercises. He said:
This lesson speaks a world of truth. Certain exercises work much better than others do when it comes to enhancing athletic performance. The key is to determine which exercises most closely match the power demands of a particular sport/event.
Is there a large initial load to overcome, as with a down lineman in American Football? Is the only form of resistance gravity and bodyweight, as with a sprinter? Is the movement executed from a stationary position as in the golf swing? The answers to these questions give you a great idea of the types of movements the athlete should be focusing on in their power training sessions. This helps transfer those base power gains in the weight room into greater functional athletic power.
Rotational Power Development Exercises
These exercises improve explosive power in all athletes because all athletic movements involve some degree of twisting/stabilization. Think of these rotational exercises as fundamental power movements for any athlete. As such, their value in any complete training program is very high and will prove very useful, especially during pre-competitive and competitive seasons to maximize power output.
This exercise closely replicates the upper body/shoulder rotation movements used in a number of different throwing and hitting movements. The one "limiting" factor of this exercise to take into consideration is that it is performed from a sitting position. Most rotational power training exercises should be performed from a standing position in order to replicate the body position demands of the sport as close as possible during training (Siff et al. 1998; Baechle et al. 2008)[2,5].
Cable Chop/Reverse Cable Chop
These are two of my favourite exercises. These exercises are excellent at strengthening the transversus, internal and external obliques and the spinal muscles of the core. Since these exercises are performed from a standing position, they are also excellent at connecting the various muscle chains from the feet all the way to the hands.

Supersetting these two exercises is a very time efficient and effective way to increase rotational power and link together various muscle chains.
Standing Trunk Twist
This exercise trains the entire core area and develops the dynamic stability and balance that is needed to maintain control of the athlete's centre of gravity once power levels increase. This is one of the exercises where speed of movement can be high without risk of injury. As this rotational exercise is performed from a standing position the improvements from this exercise transfer over well to the playing field.
Medicine Ball Tosses
Medicine ball tosses are an excellent plyometric training strategy to maximize rotational power and overall total body power. These movements take advantage of the stretch/reflex mechanism to develop and release greater energy from muscles.

General rotational power training tips
Power training comes first
The order in which power exercises are performed is as important as the actual exercises that are selected. Perform these movements near the beginning of your workout when you are fresh and execute them with maximum effort for the greatest impact (Behm & Sale 1993; Cronin et al. 2001)[3,4].
Technique is priority #1
Initially, focus on developing good form. You can progress to heavier medicine balls after 4-6 weeks. The key is to train smart. Learn proper technique first and then focus on more speed and/or resistance.
Train with eyes closed
For a change of pace, perform these exercises with the eyes closed to train spatial awareness, dynamic balance and enhance proprioceptive feedback.
Focus on balance
As rotational power levels increase a significant amount of time and effort should be put into improving dynamic balance and awareness on where the athlete's centre of gravity is.
For the best power workouts keep them short
When performing power training movements keep workouts short (under 60 minutes). As fatigue, sets in, technique will suffer. If an athlete is power training in a fatigued state it will lead to altered form, altered neural firing patterns, reduced power output and decreased performance (Siff et al. 1998).
Combine with other types of training
It is best to combine these rotational power exercises with various types of total body (both heavy and light) training stimuli at varying velocities in order to fully develop the muscular, neuromuscular and proprioceptive coordination that will improve functional performance, rotational power and total body power (Cronin et al. 2001).
Do not undervalue mental energy
Performing technical and power work requires a fresh, focus mind in order to achieve the best results. Power training benefits from an energized mindset because the increase mental energy will boost the flow of impulses from the brain to the muscles, thereby generating more power.
Perform a sport specific warm-up
This will help reduce the risk of injury, awaken the nervous system and increase the power available in both general and sports specific movements.
These tips and exercises will improve the quality of your core and rotational training. With continued effort and properly focused training, the result will be stronger, more powerful athletic movements and better performances.
