If you decide to improve your fitness and build muscle mass, there is no need to buy a gym membership at all. You can do weights at home as well. In addition to the simplest push-ups and pull-ups on the bar, you will also need dumbbells, which everyone is quite capable of making from available materials.
It is necessary
Lathe, metal blanks; plastic bottles, sand, shot; metal rods or fittings; wood board, lead
Instructions
Step 1
If you have the skills to work on metalworking machines and have access to them, make dumbbells on a lathe. The weight of one dumbbell without discs should be approximately 1.5 kg. The dumbbell diameter is about 35 mm. To fix the offset discs, cut a thread for an M20 nut (the inner diameter of the nut is 20 mm). The thread should not reach the base of the handle by 20 mm. It is better to fasten discs carved from metal with not one, but two nuts. The second nut will act as a locknut, otherwise you will have to constantly tighten the fasteners.
Step 2
Make dumbbell discs with a diameter of 70 mm and a thickness of 25 mm. In this case, the weight of the disc will be about 0.5 kg. A more accurate dumbbell weight can be selected using special washers with an inner diameter of 20 mm, which are sold in stores.
Step 3
In the absence of the necessary special equipment and materials, make dumbbells from available tools. Pick up plastic bottles that are the right size and shape and fill them with different contents. These can be sand, cement, nuts or bolts, shot and so on. Such improvised dumbbells are good because they allow you to dose the load depending on the degree of training.
Step 4
Use pipes of various diameters and lengths to make dumbbells. Unlike bottles, do not fill them with bulk materials, but fill them with lead or concrete. If desired, it is not difficult to make a set of such dumbbells of different weights. It is quite possible to use beer cans or other tin containers as a basis for dumbbells.
Step 5
Another way to make dumbbells is to use metal rods or rebar. Cut off equal-sized pieces of rods (25-40 mm long), align and wrap with insulating tape. The convenience of working with such weights is that you can change the number of rods in the bundle by controlling the weight of the dumbbell.
Step 6
You can also make homemade dumbbells from lead. Take a suitable board with a thickness of about 30 mm. Use a chisel to cut a dumbbell stencil into the board and fill it with molten lead. For greater strength, place a steel bar in the middle of the dumbbell before casting, placing a couple of bolts under it. Paint or wrap the finished dumbbells with electrical tape.
