How do I work out when I have no energy?

I am 18 and I am 6 foot. I have no idea how much I weigh but over the past year I have gained probably 20-25 pounds. When I was younger, like 14/15 I would gain weight and without a problem lose it. Now after school and working I am so exhausted I just want to go home and sleep. How do I work out and lose weight if I am so tired?

How to Burn Body Fat and Lose Weight

Recommended Answer:

You are not tired your mind is tired. Pal, everything is inside your mind. Motivation, means something to you? Lack of energy doesn't exist, motivation and persistence exist. You have goal or you are happy with yourself subconsciously?Karate tells me one interesting story about your coward part and your hero part. The coward part of yourself is the body always complaining, asking for rest, food, coke. Your hero part is your mind, staying strong -" no! you must do this" "NO! There is not big portion food this night for you, no there is no coke you will drink water". Understand? Self-motivation. If you don't have goals, if you don't motivate yourself 100 energy drinks won't help you.

Other Answers:

• You have lost muscle, that's why it is harder to lose weight. Since you are so tired, perhaps you can stay healthy and/or lose weight by dieting. Eat meat, vegetables and fruits. Grains (whole or not) and sugar should be eaten in moderation.
• Eat & sleep well and excersise regularly and you should be fine. There are things that can cause exhaustion and lack of energy like: depression, lack of iron, lack of vitamin d, (etc, other nutrient deficiencies), not eating enough/eating too much. When I eat too many carbs, I get incredibly sluggish. Eat healthy foods that are going to provide enough energy to get you through that.
• honestly their are some great legal pre workouts out their that have natural things found in everyday foods and stuff that will give you tuns of energy when i get home from work and haven't finished or started my day's workout i use c4 pre workout stuff just put a scoop in a bottle of water drink that 15 to 20 mins later i do most of my workouts at once like my 100 push ups for the day but then i slack and only do 50 of my 100 pullups for the day cause i dont wana drink another 1 and depend on them to work out all the time but it gives you some serious energy kinda like coke would but no crash and heart risks and holes in your nose scary stuff
