You have already been going to the gym. Your body is starting to respond to the hard work. People have already started to talk about you. She works too hard, I say. You are on a different trajectory however. You want to consolidate and build on the changes that you have already brought into your lifestyle. So what would you do?
For starters, hopefully exercise, eating and mindfulness has already reduced your stress loads. If not make the effort to do so. Stress and high intensity work outs do not combine well. Stress causes your body to break down in different ways. At the same time, you are straining your body. Next focus on the quality of your food, especially on the post work out protein and on eating sufficient quantities of potassium. Strangely, one of the best sources of potassium is potato (Aloo Roti anyone for the Indians?). If you are vegetarian, you might want to consider whey protein. Otherwise, it is hard to get adequate protein. Your body needs at least 7-8 hours of rest each day. You can’t make it up over the weekends. So make sure that you are getting adequate sleep. This will help your body recover from the strenuous work out. Hopefully, you have access to someone who can help you stretch your body post work out. This helps relieve muscle tension and allows you to get the best out of your work out. Finally, I know you are exhausted. However, a light 20-30 minute walk or yoga is useful. It is called active recovery. Muscles need to be worked to recover. This is the reason you go back into the gym even though your entire body may be hurting.
As with everything else, the initial stages of doing something is easy. It is when you want to start maximizing your capacity and outcomes that it gets harder. Going from 90% to 92% in something. But you would not settle, would you?
