Water Jacks are an underwater exercise adapted from their land counterpart. They are an effective way to improve your overall fitness level, flexibility, and strength and have the added benefit of water’s hydrostatic pressure, 360 degrees of resistance, and turbulence.
If you're looking to maximize your Water Jacks routine, there are a few key things to keep in mind.
Jacks require no to little equipment depending on your mobility and your fitness goals. They strongly depend on tempo and resistance.
If done slowly with no equipment there will be little to no effort required and the main benefit you will get is balance and coordination. This is great if you are elderly and need to improve those things.
Increasing your tempo without equipment may give a person of average ability the desired cardiovascular benefits. If you’re more fit and find that your heart rate isn’t at a desired rate of exertion add webbed gloves, paddles, handbells, floatation dumbbells, or noodles.
If you’re very athletic you’ll want to increase your speed to around 132 beats per minute. Additionally, you might wear resistance ankle cuffs to increase the drag on your legs because at this speed the force generated by your jacks is at its maximum power. Remember, increased surface area along with increased speed equals increased force. In land terms, you would think of this as increased weight.
No matter what degree of mobility you have, there are ways to modify your Water Jacks to get the most out of them. All the variations we outline below can be done by anyone at any level of fitness if modified by tempo and depth of water.
If your mobility is limited, you will need to do your jacks slower and in shallower water. Anything from standing in a fully anchored depth, i.e. about waist high, to partially anchored, i.e. chest deep.
With added mobility and strength you will want to do your jacks in partially or fully suspended, i.e. neck deep or off the pool floor, and faster. Wear a flotation belt so you don’t need to fight to stay afloat.
Here's how to do a basic Water Jack:
- Start with your feet together, hands down by your hips.
- With a slight hop move your legs out to your sides while raising your arms up to the surface of the water.
- Focus on engaging your core and keeping your back straight, while maintaining powerful posture.
- Return to feet together with a slight hop and deliberate force pulling in on the legs and down on the arms.
- Repeat.
Variations of Water Jacks:
One-legged Jacks. This exercise is often necessary if you have very limited mobility and cannot do a hop. When you are standing in water fully anchored, you will be able to feel the pool floor under you. This allows you to use your balance on one foot as a stable support. When you do a one-legged jack you can feel your core muscles using an isometric contraction to keep you upright. Simply extend one leg and both arms out with as much force as you can muster, and return with same force. Follow this with the other leg and alternate for as long as you wish to do this exercise.
Opposite arm Jacks. As the name implies, you have to concentrate to drop your arms when your legs go out and raise your arms as your legs come in. This is the best way to do jacks fully suspended in a floatation belt. You will have less bobbing up and down when your arms oppose your legs.
Diamond Jacks. Similar to regular jacks, your arms and legs are coordinated except the hop travels forward, center and back. This pattern moves both legs forward when your arms are back, you jump wide center, then both legs jump back when your arms are forward. It is a great brain and coordination builder.
Tuck Jacks. Incorporating a core crunch into the center of your jack takes full advantage of water’s buoyant nature. You hop out wide coordinating arms and legs, then jump up into a tuck using your abdominal muscles. Return to a wide jack from the tuck and you’re ready to do it again.
Frog Jacks. Similar to a tuck jack except your legs are turned out from the hip as you jump up, knees bending with your feet rotated inward, pull feet together in a frog shape. Return to a wide jack keeping the heels inward and toes pointing outward.
M&M Jacks. Like a regular jack, your arms and legs are moving out and in together. M&M shapes are created standing with your legs together, tuck up center, jump out into a jack, tuck using core, and return to standing center.
All of these jacks variations are applicable to any level of mobility with modifications. For a full explanation of modifications download the Ability Fix app or go to the YouTube channel, http://YouTube.com/AbilityFix
As with all exercise there are some safety concerns that need to be addressed. I am a big supporter of “if it hurts - don’t do it”. Of course, "if it feels good do more of that" applies as well.
Ask your doctor or physical therapist to give you more guidance if you have had surgeries.
If you are doing this aerobically make sure the water temperature is cool enough. I recommend 88 degrees (F) or less.
Keep your powerful posture. Poor posture strains the wrong muscles and will make this exercise less effective.
Wearing shoes protects your feet, supports your arches and cushions your heels.
Floatation belt usage allows you to focus on the exercise and not struggle to staying afloat.
In conclusion, Water Jacks a great way to do a low-impact exercise that doesn't put strain on your spine because there is no twisting or bending.
By following these tips, you can maximize your Water Jacks exercise and get more out of your water workouts. They are an effective way to improve your overall fitness level, flexibility, and strength, as well as strengthen your core muscles, improve balance, and increase cardiovascular capacity and endurance. Give it a try and see the difference it can make in your fitness routine.
