Klay Thompson Workout and Diet

Professional Basketball Player

Born: 1990

Klay Thompson was born in Los Angeles. His family moved to Oregon when he was 2, and then back to California when he was 14. Both Thompson’s parents are athletes. His mom played volleyball on a collegiate level and his dad played in the NBA. Thompson was named to the Pac-10 All-Freshman while playing for Washington State University, and the All-Pac-10 First Team as a sophomore and junior. After his junior year in college in 2011, he entered the NBA draft and was picked up by the Golden State Warriors. In 2014, Thompson and teammate Steph Curry earned the nickname ‘the Splash Brothers’ for their record-setting 484 combined 3-point shots. In 2015, he helped the Warriors make it to the NBA Championship for the first time since 1975. The Warriors won again in 2017 and 2018 and Thompson is a 5-time All Star. Injuries in 2019 led to his missing almost 2 1/2 years of play. Thompson returned in January of 2022, helping the Warriors win a 4th championship. He has millions of followers on social media. Thompson is 6 feet, 6 inches tall and weighs about 220 lbs.

Klay Thompson’s Diet

Like most pros, Thompson takes his diet seriously. Also like most people, he loves carbs, but he has had to dial them back. He says taking 2 years off forced him to seriously scale back his diet, and this started with carbs. He focuses on lean protein, along with sides of healthy fats and complex carbs. His protein sources of choice are eggs, chicken, steak, and protein bars. Fats include avocados and almond butter. His go-tos for healthy carbs are oatmeal and fruit. He also makes an effort to avoid junk food. He takes in a lot of water every day, and his favorite recovery snack which doubles as a treat is chocolate milk. He also drinks a lot of kombucha, a fermented tea drink which is great for digestion.

Thompson on his diet

My diet is pretty diverse.

Klay Thompson’s Workout Routine

Workout Routine

It Was Fate

Thompson’s dad Mychal Thompson was the #1 pick in the 1978 NBA Draft and his mom played volleyball in college. His parents even discussed the fact that their kids would turn out to be pros.

Injury Intervenes

Thompson says that his double injury of a torn ACL during the 2019 Finals and then a torn Achilles caused him to re-evaluate his diet and training routine.

Recovery Matters

As part of his recovery routine, Thompson does cold-water therapy, which he says really does a great job of getting the blood flowing.

Daily Dose

Thompson hits the gym about 4 days a week and he works out with the team most days. After a half-hour with the physical therapist, he’ll do strength training and then hit the court for drills. On a non-game day, he’ll spend about 2 1/2 hours training.

Maintain Rather Than Gain

Thompson isn’t into heavy lifting. He’s more likely to use bodyweight, kettlebells, and resistance bands to maintain his strength rather than trying to bulk up.

Ongoing Rehab

Thanks to his multiple injuries, Thompson now does rehab first each day before heading into practice. He spends about 30 minutes on physical therapy before moving on to his regular training.

11 Rules of Klatheism

His ’11 Rules of Klatheism’ (based on his jersey number) were created during his tour of China and include such gems as ‘Klay’s brain cannot multitask’ and ‘Lack of consciousness is the highest form of consciousness.’ Another fun fact: K is the 11th letter of the alphabet.

All in the Family

The entire Thompson family is blessed athletically. Thompson’s older brother Mychel played for the NBA for a time, and his younger brother Trayce is an outfielder for the Cleveland Indians.

Unique Superstition

Thompson has the habit of flipping a kettlebell before a game to see how things will turn out. If it lands right side up, that means it’ll be a good game.

Puppy Love

Sure Thompson has millions of followers on social media, but his English bulldog Rocco is an Instagram star. Thompson says they’re best buds because Rocco loves him no matter what.

Secret Hideout

Thompson bought a house in San Francisco, but other than letting it slip that it’s near a dog park, he’s not telling anyone where exactly he lives.

Thompson on his sleep requirements

At least 8, but if I get 6 or 7, I’ll be okay. I’ll just need that pre-game nap.

The ocean has been such a huge source of recovery for me.

Thompson on his dog Rocco

He didn’t care the day before I signed the contract or the day of. He just loved me for me.

One of Thompson’s ‘Klatheistic’ rules

Doing is better than talking. Since when did trash talk become the trend in the NBA? Actions speak louder than words.
