It's not easy but it's very simpleDamn i thought yall would have some crazy tricks to get fit fast
Eat less, do more 35lbs in 3 months (~13 weeks) is ridiculous though, you might as well throw your summer in the garbage.
Then again, if you really are 16-19% and you want to get down to 10%, you won't need to lose anywhere near 35lbs. So one of your parameters is wrong.
