Remember, you are not merely trying to pull your heavy bow back. You’re striving to shoot it with good form, which requires a clean release. Toward this end, make sure to leave room for microexpansion as you approach your bow hand anchor. Microexpansion is the final phase of expansion that occurs at the tail end of your draw. Once you’ve fully settled into your back, continue to gradually expand toward release to ensure collapse never occurs. This requires a controlled, focused state, but will pay dividends in ensuring an ideal release.

Medial rotation of your bow elbow—both predraw and during draw—is an essential component to handling heavy bows. It aids in joint alignment and encourages scapular depression (the settling of the bow shoulder) by reinforcing use of the latissimus dorsi and pectoral muscles. Be careful to not hunch your bow shoulder as you rotate your bow elbow.

Maintaining an inward angle with your bow arm—both predraw and during draw—will help you avoid straining minor back-side scapular muscles. It also allows for a natural cant. An inward bow arm angle also prevents string slap.

Hook configuration has the potential to greatly impact your ability to draw a heavy bow. A common misconception when it comes to using thumb draw with war bows is, “Man, you’re gonna destroy your thumb.” Luckily, your thumb is an incredibly strong apparatus, and using it correctly with heavy bows will result in risk- and pain-free shooting. The thumb tendon will develop as you exert load. As with any exercise activity, if there is discomfort, take a rest day.
A major theme you will recognize throughout this article is that the guiding principle when it comes to proper technique is to achieve relaxation by conforming to the body’s natural angles, and the draw hand is particularly important in this regard. For this reason, the common criteria for an efficient heavy draw hook is 1) thumb pad comfort and 2) the ability to reduce effort in draw hand wrist and joints during the draw.
The first variable when it comes to your hook is depth. Hook depth refers to which section of your index (and middle, if using a double hook) contacts the thumb. With a shallow hook, the primary point of contact is the distal joint. With a deep hook, it is the intermediate segment of the finger. For drawing heavy bows, a deep hook is recommended, as it promotes greater stability, comfort, and relaxation in the draw hand.

Position of the hook
The second variable is the position of the hook on the thumbnail. For pulling heavy bows, your primary hook (index) should contact the thumb behind the nail in order to fortify the hold (see below diagram).
Orientation of the thumb
The third variable is the orientation of the thumb: slanted versus orthogonal (perpendicular). A relaxed, slanted thumb angle provides a more natural resting state for the hand, and therefore a more comfortable pull (see below diagram).

Depending on your anatomy, the ideal goal of a deep hook behind the thumbnail with a slanted thumb may or may not allow for a double hook. If you find your middle finger cannot comfortably sustain contact with your thumb whilst drawing, it is recommended you transition to a floating single hook. The goal of a floating single hook is to retain the stability and comfort associated with a double hook. A floating single hook deviates from the more widely known anchored single hook by untethering the thumb from the middle finger (hence “floating”) whilst maintaining a deep hook behind the thumbnail with the index.
In conclusion, whether it’s a floating single or a double hook, a deep hook behind the thumbnail and a relaxed slanted thumb will provide the most stability and comfort for drawing a heavy bow.
