How to turn a garden shed/backyard shed into a gym?

Clean Out the Gardening Tools

The first step in turning the garden shed into a gym is to clean out the shed of all the garden equipment. Get rid of all the machines and tools you don’t need; find another storage place for the ones you need.

You can spare some space for the gardening tools and machines in the shed after you are done setting up the garden gym. But you need to clear it out completely in the beginning.

Clearing out will provide you a fair idea about exactly how much floor space you got and what gym machines you can fit in there. Also, when you clear out the wall fittings, you can use any wall to support or fix the racks or other gym equipment.

So, start clearing out the shed before making any purchase for the new home gym you are planning to build.

Now as you have cleared the shed, you can easily measure the length, width, and height. You need to the sizes to know which and how many pieces of equipment you can fit into it.

If you are going to build a gym shed in the empty space you have in your backyard then you can choose shed size considering the pieces of equipment you wish to put into it.

Most probably your shed isn’t as big as your commercial gym club. That means you won’t be able to fit all those machines in your shed. Some of the machines might be longer, wider, or taller than you shed itself.

Thus, you need to extra choosy about the equipment you choose based on your shed size and exercise requirements.

To ease this task, here we are providing the average sizes of the most popular exercise machines. All sizes are mentioned in inches and in length/depth, width, height sequence.

Ceiling Height

Some big exercise machines are taller than 84 inches. Many backyard gym sheds have ceiling height equal to or lower than that. That makes it important to measure the height of your shed and know the height of machines you are considering for adding into the gym.

The average heights of the most popular and versatile pieces of gym equipment are mentioned below. If you are starting from scratch, you should build a gym shed that is about a foot or two taller than the tallest equipment you want.

  • Treadmill: 48 – 60 inches
  • Exercise Bike: 42 inches

Shed Gym Floor

The floor of your shed home gym needs to have much better qualities than your regular shed floor. It has to provide cushioning to protect your joints when you are performing jumping jacks or similar type of high-impact exercises.

The gym floor has to support the falling weights while reducing the noise of the fall. It has to be strong enough to handle the impacts weight falling or you jumping over it.

Common concrete floors, marble floor, or glazed tile flooring won’t be suitable for the home shed gym. Here are the recommended floor types for it.

Protect Shed Gym Floor with a Flooring Mat

Changing or altering the whole flooring while building a workout shed might be expensive or infeasible in some cases. But that doesn’t mean you have to make do with the inferior dysfunctional gym shed floor.

There is an option to protect the gym floor using the gym flooring mats. The mats come in various shapes, sizes, and materials.

The heavy-duty, high-density, impact-absorbing, scratch resistant, washable gym mats can protect the floor and the equipment from any damage. At the same time, the mats can help to reduce the noise of the impact of weights falling on the floor.

The mats also provide a grippy surface to workout safely and some cushioning to protect your joints. Following are the type of mats that are recommended to be used while building an outdoor gym or a workout shed.

Electricity – Power Up Your Garden Shed Gym

You need the electrical power for running some gym machines. So, you need to power up the shed in case it doesn’t have a connection already.

The electrical power supply boxes in your home shed gym should have some extra sockets considering these will be needed for the fixed as well as movable gym installations.

Apart from the machine, you should consider the electrical connection requirements for your cooling fans, lights, exhausts, music, etc. while designing the layout for electrical wiring.

This has to be done after you select the gym machines you are going to install, as it would give you a fair idea about how many power points you will need for the installations and lighting. Have a few extra would cost you a little but would come in handy if you decide to add some equipment at a later stage.

Shed Gym Lighting

One of the prime purposes of building a backyard shed gym is to be able to work out at any time of the day. And that won’t be possible if you don’t have enough light to perform the exercises.

You can add some windows to allow sunlight into your shed so that it would have enough light in the daytime. But for working out in the early morning or in the evening after sunset you would need to install some lights.

The lights shouldn’t be too bright eye scorching or too dim to see your feet. Most of the light sources that you use at your home can be used to light up your shed gym. If you are confused about which one to use, here are some recommendations.

Set Up Air Circulation & Ventilation in Your Workout Shed

The shed is made to store the gardening tools and not for human presence. The ventilation is so poor in some garden sheds that even standing idle can make you uncomfortable.

While working out better air circulation and ventilation is needed as you generate more body heat and breath heavier. So, to be able to use the shed gym for more than a few minutes, you must optimize the air circulation in your workout shed.

Keeping your shed airy and comfortable can help you exercise for a longer duration and expedite the results. Along with keeping the shed naturally and cross-ventilated you can use some air circulation products to better the shed gym environment. Here are some suggestions on the products that would improve the airflow of your shed gym.

Garden Gym Insulation

Your shed can get too hot or too cold very fast if it isn’t insulated properly. Even if you install high tonnage air conditioning unit in the shed, it will just burn too much power and still won’t be able to condition the temperature without good insulation of the shed walls and ceiling.

You need to install a layer of insulating material that doesn’t conduct heat. Install it all along the walls and ceiling of the shed. If you are planning to cover the flooring with gym mats then the floor doesn’t need to be insulated.

Among the many insulation materials following is the list of products that are easily installable, non-toxic, and last very long.

  • Pre-cut rockwool sections
  • Fibreglass rolls
  • Foam boards
  • Loose fill insulation for the gaps

Shed Gym Equipment

The shed is smaller than the big gym club, you can’t fit in too many gym machines in it. But for faster results and to target specific muscle groups you need to perform different exercises, and for that, you need to have the requisite equipment.

The best way to tackle this issue is to get a few versatile pieces of equipment than getting way too many single-function machines. These multi-functional pieces of equipment might take up the space of two or three single-function units but can offer you a platform for tens of exercises.

The most popular multifunctional types of equipment are power cages and power towers. These coupled with some weights and bars can be used to perform a wide range of exercises. Depending on the size of the shed you can go for a full power cage, half rack, or even a smith machine if the shed is big enough.

If you are looking for some suggestions or recommendations for the products in this section, refer to the list below.

Weight Storage Units

If you are thinking you won’t need the weight storage unit as only you will be using the shed gym, then you plain wrong. When you are low on space keeping the weight plates and dumbbells spread all over the place will only create more issues.

The weight storage units not only help you keep the weight plates stored in an aesthetic manner but also makes them easily accessible. The weight storage units also allow you to utilize the spaces which otherwise would go unused.

Some storage units can be installed on the wall or hanged to the ceiling to save on the floor space. You choose any one among the thousands of weight storage racks available on the internet or can just save some time and choose one among the best ones mentioned below.

Secure your garden shed gym

Once you are done with all the steps right from clearing out the clutter to installing the last piece of equipment, it is time to secure your investment.

Those machines and the weights in your gym don’t come cheap. You will recover the investment in a year or so if you compare it against the cost of a gym membership, but if you keep losing the pieces of equipment to theft every month, you’ll be losing money, time, and eventually your interest in maintaining the shed gym and working out in it.

To avoid all these unpleasant things, you need to secure the shed as firmly as you can. The products listed below would help you do just that at a very small cost.
