3. You don’t have the right equipment
At first you will be able to work out without any equipment, but over time it will become more and more difficult to load your body properly. Moreover, some muscle groups you will not be able to pump at all without sports equipment. For example, you will not be able to load your back without a bar, and your legs – without weights.
How to fix it
If you want to progress, buy a minimum set of equipment for home training: a bar, collapsible dumbbells and weights weighing 16 kg, a jump rope, a set of tape-expanders with different resistance, training loops.
All this equipment can be placed in a small nightstand. At the same time, your workouts will be many times more effective – no worse than in the gym.
