Hey guys, I'd like some feedback on my exercise routine. My goal is to lose 10-15 pounds in 3.5 weeks. Considering I'm starting at 200lb, I think it's reasonable. I am running 5km five out of seven days, doing 20 minutes of abs every second day, and weight lift twice a week (likely for ~20-30 minutes). I have cut greasy food out (the most greasy I'll have is a bun with breakfast/lunch), drink no pop/sweet stuff, and only plan to booze on the weekends.
Is this enough? Thoughts on improvements I can make to meet my goal?
