When you practice yoga, you train, in addition to agility, also strength and balance. Yoga is a form of exercise that stretches the muscles and strengthens the weak muscles. As you get to know the exercises, you will gain greater muscle strength. At the same time, yoga has a strong focus on breathing, which is used to challenge endurance, so the exercises in step with the increased muscle mass will be both easier to perform and to last longer.
Whether you can lose weight by practising yoga solely depends on whether you burn more calories than you consume. You can lose weight by only practising yoga, but since it is usually training with low / moderate intensity, it will take longer before it can be seen on the weight, compared to if you combine with practising for example cycling (moderate / high intensity ). In addition, I would recommend you variation based on the public recommendations, which is to practice at least 2 x 20 minutes of high-intensity exercise weekly. High intensity is training that causes the heart rate to rise to a level where it is difficult to have a conversation. In addition, high-intensity training benefits by increasing muscle mass faster, while giving you a higher after burn, which is also beneficial for weight loss.
In general, it is not recommended that the same muscle groups be challenged by hard training every day. This is because you break down muscle fibres during exercise, which must have time to recover and rebuild itself so that they become stronger for the next workout. However, yoga is a more gentle form of exercise, which is why I estimate that you could sometimes sneak a few yoga days into the line. However, I would still like to point out that you make sure to recover, especially as long as the form of exercise is new to you and your body is not used to it. For this, it should also be mentioned that for some (for example, hyper mobiles) it can also be a bit stressful for the joints in the beginning, so it is also worth keeping an eye and notice for here.
At the same time, I would recommend variation and a slow escalation of the training for the sake of motivation, so that you do not put in too much effort - and you continue to want to train. After all, it is regular exercise that in the long run will help you both reach and maintain a possible weight loss.
