Does cramming a ton of exercise into 1-2 days per week work just as well as spreading the same amount of exercise across 5-6 days for losing weight?
Don't cram, you can overtrain and increase your appetite while reducing muscle mass, causing you to gain fat quickly.
Regular and consistent exercise with 2 to 3 strength sessions spaced out every week over a long period of time will help you to invest in building muscle mass which helps you to increase your metabolism.
Regular and consistent cardiovascular training also helps you to regulate hormones that cause you to lower cortisol, the stress hormone. Reducing cortisol helps you lose weight and build muscle, so it's a win win.
Most importantly, the point of exercise is to prevent health issues like high blood pressure, diabetes type 2, some cancers, low bone density and osteoporosis, high cholesterol, depression, and memory loss. Exercise also helps you to feel energized, optimistic, and helps you sleep better.
Instead of focusing on the weight, try to be motivated by all the good health benefits it will give you. The fat loss will be a byproduct of consistent exercise.
