I'll echo everyone else. Diet and cardio. Its impossible to do 16 weeks of work in 4. Lots of people think they can start training in april and may and go from %20+ bodyfat to shredded 6 pack abs in a month and a half.. Even with AAS it doesn't work that way. So between now and end of june if your diet is super on point and so is your training you could possibly lose 6-8lbs of fat if you're genetically gifted you won't lose much muscle in the process
