Bruce Lee trained with a mix of barbell work, martial arts practice, running, and obsessive core and forearm conditioning, often logging multiple sessions per day. His approach was unusual for the 1960s and 70s: low-volume strength training, high-repetition abdominal work, and a philosophy of borrowing techniques from any fighting style that proved effective in real combat. At his peak, he stood 5’8″, weighed between 130 and 140 pounds, and carried an estimated 5 to 6 percent body fat.
His Strength Training Was Surprisingly Brief
Lee’s barbell sessions lasted about 20 minutes and happened three times a week, typically on Tuesdays, Thursdays, and Saturdays. He kept the volume low, doing only one to two sets per exercise with a moderate rep range of 8 to 12. The routine he eventually settled on looked like this:
- Clean and press: 2 sets of 8 reps
- Squat: 2 sets of 12 reps
- Barbell pullover: 2 sets of 8 reps
- Bench press: 2 sets of 6 reps
- Good mornings: 2 sets of 8 reps
- Barbell curl: 2 sets of 8 reps
For legs, he favored higher repetitions, aiming for 12 to 20 reps per set. The weights were not heavy by powerlifting standards. His squat, for example, was logged at around 43 kilograms (roughly 95 pounds) for 3 sets of 10 in one of his early 1960s training notebooks that recently went viral online. The point was never maximum load. Lee trained for functional strength and speed, not size.
His earlier programs from the mid-1960s were more detailed and included concentration curls at 16 kg for 4 sets of 6, tricep extensions at 29 kg for 4 sets of 6, reverse curls, wrist curls, calf raises for 5 sets of 20, and sit-ups for 5 sets of 12. These journals show a man who tracked everything and adjusted constantly.
Core Training Was a Daily Obsession
His wife, Linda Lee Cadwell, described him as “a fanatic about ab training,” saying he was always doing sit-ups, crunches, Roman chair movements, leg raises, and V-ups. This wasn’t a quick five-minute finisher. Lee’s abdominal routine was a standalone workout with high repetitions and four sets per exercise.
A typical session included waist twists for 90 reps (sitting in a V position and rotating side to side, touching the floor with clasped hands), sit-up twists for 20 reps alternating left and right, straight leg raises for 20 reps, and frog kicks for 50 reps. The total volume per session was well over 150 reps across multiple movements, all targeting different angles of the midsection. This kind of high-rep core work, performed almost daily, is a major reason his abdominal definition became one of his most recognizable physical traits.
Forearm and Grip Work Throughout the Day
Lee’s forearms were disproportionately developed compared to the rest of his compact frame, and that was intentional. Strong forearms and grip translated directly to punching power and the ability to control an opponent at close range. He dedicated specific training sessions to this area and also squeezed in work during downtime.
His forearm exercises included wrist rollers (a rod with a rope and light weight that you wind up by rotating your wrists), fingertip push-ups, reverse curls, seated barbell wrist curls with palms up and palms down, and Zottman curls, which combine a standard bicep curl on the way up with a reverse curl on the way down. He also used leverage bar curls and rotations, gripping a dumbbell by one end and curling or twisting it to challenge the wrist in unusual angles.
One of his personal training rules was to carry a sponge gripper and use it daily as much as possible. He also had a custom gripping machine built for his office and cranked out reps on it between tasks. This kind of passive, all-day grip work is something modern athletes are only now rediscovering.
From Wing Chun to Jeet Kune Do
Lee grew up in Hong Kong studying Wing Chun under the legendary Ip Man. Wing Chun gave him his foundation: centerline theory (the idea that attacks and defense should travel along the shortest path between you and your opponent) and the concept of simultaneous blocking and striking. These principles stayed with him for the rest of his life.
The turning point came around 1964, after a private duel with martial artist Wong Jack-man. Lee won, but felt the fight had taken too long and exposed the limitations of relying on any single system. He began dismantling his own approach, studying boxing, fencing, wrestling, and other styles to find what actually worked in live, unpredictable combat. By 1965, he was publicly outlining the concepts of what would become Jeet Kune Do, though he resisted giving it a formal name because the whole point was to avoid rigid systems.
Jeet Kune Do borrowed stop hits and stop kicks from European fencing, the idea being to intercept an opponent’s attack with your own strike rather than blocking first and countering second. It pulled footwork and head movement from Western boxing. It kept Wing Chun’s trapping techniques but simplified them over time. Lee’s later training, particularly what he taught privately to student Ted Wong, placed greater emphasis on elusiveness and stripped-down efficiency rather than the more complex trapping sequences of his earlier years. The philosophy was simple: absorb what is useful, discard what is not, and add what is uniquely your own.
What He Ate
Lee avoided dairy and leaned heavily on high-protein, vegetable-rich meals drawn largely from Chinese cooking. A typical breakfast was steak and eggs with sautéed greens. Dinner was often chicken stir-fry with lots of vegetables, or his reported favorite: beef in oyster sauce. These meals were straightforward, built around protein and produce with relatively little processed food.
He also blended a daily protein shake that, by modern standards, sounds intense: one or two raw eggs with the shell included, non-fat dry milk powder, banana, wheat germ oil, peanut butter, brewer’s yeast, granular lecithin, and inositol (a compound related to B vitamins). The shake was designed to pack in calories, protein, and micronutrients in a single glass.
On the supplement side, Lee experimented broadly. He took vitamin C, vitamin E, a B-complex, multivitamins, protein powder, wheat germ oil, royal jelly, ginseng, and bee pollen. Some of these have solid evidence behind them (vitamin C for recovery, B vitamins for energy metabolism), while others like bee pollen and royal jelly were more speculative. Lee treated supplementation the same way he treated martial arts: try everything, keep what works.
Why His Approach Still Holds Up
What made Lee’s training distinctive wasn’t any single exercise or routine. It was the integration. He combined short, efficient strength sessions with daily core work, constant grip training, martial arts practice, and cardiovascular conditioning. He tracked his workouts in detailed journals. He adjusted his programs regularly rather than following the same plan for months. And he kept his strength training volume deliberately low, which allowed him to recover quickly and train martial arts techniques with full intensity on the same day.
His body fat percentage of 5 to 6 percent at a bodyweight of 130 to 140 pounds reflected someone who was training for performance, not aesthetics. Every pound had to contribute to speed and power. The 20-minute barbell sessions, the high-rep ab circuits, the all-day grip work, the cross-disciplinary martial arts study: these weren’t separate programs. They were pieces of a single system designed to make one person as fast, strong, and adaptable as possible.
