The Wrath of Khan
The enduring comeback of bodybuilding’s underground sensation Zack “King” Khan
Let’s go back to June 8, 2010, when you ruptured the tendons in both knees hack squatting with 700 pounds. Did you learn any lessons from that experience?
I don’t know what lessons I should learn. People say to me I must have used too much weight, but I’d done that weight dozens of times before. I’d done it before for 15 reps. And there was no sign of it [the injury] coming. I blasted up the first two reps easy, and then on the third rep I heard a big pop and one leg gave out. All of a sudden, the weight came down on me, and then the other leg popped because I had all the weight on it. If I had some signs, I wouldn’t have gone as heavy. You listen to your body and follow the signs.
In the aftermath of the June 10 surgery to reattach the tendons, what did you think about your bodybuilding future?
Lying in the hospital, I thought everything was over. I’d lose my sponsorships, and I’d never compete again—and this after I’d just gotten my pro card [by winning the 2009 IFBB British Championships]. I just kept thinking about Jean-Pierre Fux and what happened to him. [Once a top pro, Fux ruptured both knee tendons squatting 700 at a photo shoot in 2002. He competed only once afterward and failed to place.] His pictures came to mind, and I wondered if I’d even be able to train again.
What were your legs like during those first weeks of recovery?
When did you start to get some strength back?
What was it like when the braces came off?
It was the weirdest feeling. It felt as though if I bent my legs a little bit I’d fall on the floor, even with the crutches. And I’d lost so much mobility and muscle strength. I was like, “Oh, my god, look at the state of my legs!” But I told myself there are two ways I can go. I can go back to the dark and dig myself in so deep I can’t get out, or I can take every day as it comes and build up a routine and slowly but surely bring myself back. Some days were really depressing. I’d stay in bed for 12 hours. I was just overwhelmed when I’d think that everything I aimed for was gone. So it was like I was fighting with I’d do high-rep sets of leg extensions with no weight at home. I’d do 5 sets of 50 in the morning and 5 sets of 50 in the evening. And then when I built up the strength that way, I was back in the gym and doing very light leg extensions.
Sometimes I’d look at a website and they’d say, “Zack Khan’s finished.” People can be really cruel behind the computer. It did sometimes get to me. But I just thought they don’t know how determined and focused I am. I knew then, I’d do everything I could to prove them wrong.
You had a huge setback in December 2010. Tell us about that.
I started making decent progress, and then in December I got an infection in my left knee, and they had to operate again. So that really set me back. They had to cut the tendon totally off again and reattach it again. I was right back where I was before with a cast on for six weeks and then a brace after that. Mentally and physically, that was really devastating.
So you had to go through the whole process of just regaining the strength and mobility to walk again. When did you start training legs again?
Not until June , and I had to start all over again with no weights and then really light weights. It’s really hard coming back from injuries like this. It’s like every day was a battle with myself.
I saw a video of you bench-squatting last December, and you maxed out with 135. As of January 2012, what were you squatting?
You used to squat 550 for 8 reps. Do you think you’ll ever get back there again, and do you even want to get back there again?
The last time you trained legs, what did you do?
I did leg extensions for five sets, and I went up to 60 pounds. I did leg curls for five sets, and I’m basically as strong as ever on those. I squatted for four sets with a bench and then four sets without a bench. And then I ended with leg presses on a Smith machine [lying on his back and pressing up on the bar] for four sets with two plates per side [180 pounds total].
Is there anything you do to help your legs other than your weight training and cardio workouts?
I get deep tissue massage, and I use heat therapy. I use these microwave heat bags, and I put them on my knees for like 10–15 minutes at a time to help the recovery of the tendons. I take extra care of my legs now. I make sure when I train I wear Under Armour tights to keep the heat on my legs.
What do your legs look like now?
I’ve been taking pictures, and I think people are going to be surprised by the progress. Everybody wants to see, so that’s why I’m keeping them covered for now, building the suspense.
How is your upper body?
My upper body is as strong as ever. I’m benching four plates  for reps. I’m doing 100-pound dumbbell curls, pushdowns, and pulldowns with the full stacks, shoulder pressing 140-pound dumbbells.
Do you still work with Neil Hill?
At the moment, no, because Neil is a contest prep coach, so at the moment there’s not much Neil can do for me. I have to listen to my own body and make my own way back.
Tell us about your gym in Sheffield, England.
It’s called ZKK Underground Gym. [ZKK are his initials.] I had another gym before, but the landlord wasn’t making his payments. So I looked around and found this small space. I can fit the main equipment in there, but it’s so small that I’m very selective about customers. I have about 20 members there, and that’s enough.
That bloody hack squat machine [that he blew out his knees while using], I never wanted to see that bloody thing again! [laughs] I got rid of it. For more than a year, I didn’t really need any leg equipment, because I wasn’t training legs, and the gym doesn’t have much room. Now, though, I’m shopping for a leg press. I’ll get everything I need.
What’s a typical day like for you?
I wake up and do 20 minutes of cardio at home on a bike or treadmill. Then I eat breakfast and cook my meals for when I’m at work. I work at the government employment service, helping people get jobs. Luckily, I have breaks that allow me to get my meals in. Then after work, I go home and eat again and go to the gym and train. Afterward, I eat and check my emails and get merchandise orders [from his website] ready to go out the next day before I go to bed.
Everyone is waiting for you to make your pro debut. When are you going to compete again?
I’ll compete once my legs are up to scratch, and I show a picture [of his legs] to close friends I trust, and they say I’m ready. If I have to give it a bit more time, I will. I can’t rush muscle growth. I haven’t really had a proper leg workout since the accident in June 2010. At the moment [January 2012], I’m just training to get my strength back. But I haven’t started training the way I need to train to stimulate growth. I need to use heavier weights, and I need to have at least a few months of heavy training. Hopefully, the latter part of the year I can get onstage. So if I do one of the shows in October, I will have to start dieting in July. So we’ll see how I look in June and see if it can happen this year.
The main reason to get back onstage is to prove to myself that I did what I set out to do in the beginning. There’s no question about it—I will get onstage again. It’s just a question of when. I look forward to making some great progress and sharing that with everyone. Let’s just see what happens this year, but I can say there will be some surprises.
