The average person (what, they really exist!) can easily heft about 100lb with 1 hand on a standard bar. To up the weight endlessly is a great way of improving grip strength and has a direct effect on crush training - similar to grippers. For a twist on this conventional method, thick bar/fatbar training was introduced. Your numbers rapidly drop as a result of the thickness of the handle used - which can be anything up to and beyond 4" (10cm). As the hand cannot fully close, the thumb plays a dominant role in stabilising half of the lift: with a standard lift the thumb simply wraps over the fingers to "lock" the grip. Now we realise the potential problem with thick bar training- its main focus is on a training area that for most people is not only under-developed, but even for many athletes, rarely trained - the thumb. While pinch training works the thumb more than most conventional lifts - nothing competes with thick bar for thumb building.
Try a simple experiment -
Hold your hand out in a pinch position "U" shape and tense for a few seconds. The main work areas are the palm and fingers-as indicated by the strain on the back of the hand.
Now hold the hand in a "C" shape to represent a fat bar lift and tense again. The focus shifts to the thumb and thumb pad indicating their use in this hand position.
The important factor in increasing your thick bar lifts is how strong your thumb is. So here we will discuss the best ways to train the thumb in isolation.
The obvious exercise is directly related to bar lifts - the thumb closing towards the fingers like a claw action. However, this does not mean your thumb cannot benefit from indirect training angles and exercises as we shall see. Especially when attacking the Inch dumbbell - some thumbs angle away past the small finger in an attempt to get better contact.
Here are some easy exercises with a weight and a Close The Gap Strap that can be performed for a few minutes daily. You will see you fat bar work rocket and your thumb strength hit new levels!
Ex 1. Thumb curl
![]()
The arm is held up straight and the thumb is isolated, using a strap on the end of the thumb to lift the weight.
![]()
Ex 2. Palm rotation
![]()
With the palm starting in a flat position, rotate the hand 90 degrees to vertical and back to horizontal. Keep the thumb in strict isolation for maximum effort.
![]()
Ex 3. Palm tilt

As in exercise 1 - begin with the arm facing up like the thumb curl, but tilt the hand forward - keeping the thumb strict throughout the range of motion.

The great thing about these exercises is they require minimum equipment and you can train for reps or weight to vary your routines. Happy lifting!
