bro if hes 5'9 at 290 then hes more than 30lbs over weight, your friend needs to do cardio and eat better, bieng fat for most people is a choice...they have the time to go to the gym but choose not to, he really needs to start on the basics first, and since hes already overweight id tell him to stay away from clen because that would add to the stress on his heart...Madmax
