Make your own "Thrower's" Pants
from regular sweatpants.
Tony Dziepak, December 1997
This article tells you how to convert regular sweat pants into pants that fit a thrower. The procedure involves taking some material from the lower leg and adding a diamond insert into the crotch area. This will give the sweat pants more leg and hip space and make it less tight when squatting or stretching. Also sometimes you can trip on baggy sweat pants when you are stepping through on a tight hammer turn. This alteration will remove that baggy material. Works best with a pair of sweats that are tight in the hips and quads, and baggy in the lower legs below the calves. I have been doing this all my life since high school with most of my sweat pants and sometimes other pants.
The diamond crotch can also be done to jeans and other pants, but I recommend that you practice with sweat pants first. Another option is just to add a diamond insert with extra matching denim material. You will need one pair of XL or XXL sweat pants and a sewing machine.
First thing to do is to undo all the stitching on the inseam from the top of the crotch all the way down both legs. Turn the pants inside out and cut the stitching with scissors or a sharp razor knife. Cut and remove the rubber band gather at the leg cuffs. If the elastic is sewn in, just cut it at the inseam, and leave it. Now some sweat pants will already have a small diamond panel at the crotch. If so, cut right across the panel in a straight line to connect the cut of the two legs.
Next, you want to remove a wedge (triangular) piece of material from the lower legs as shown in this first figure. Remove the piece from the rear of the inseam. Starting at the bottom of the leg, the width of this piece should be 3-6 inches (8-15cm). This depends upon how much room you want to add to the crotch and how much you are able to take from the lower legs. I would say the absolute minimum opening you must leave for the lower leg would be 12 inches. (30cm) But these make it look a lot like women's leggings. I would prefer 14 inches (35cm). The maximum without an elastic cuff would be 16 inches (40cm).
The length of the piece can be one third to one half way up to the top of the crotch. One third is good if you are the bodybuilder type that has large teardrop lower thighs and large calfs. One half is better for those that have high thigh inserts and average calfs. The piece should taper in a straight line.
Then take the two wedges and sew them together to make a long diamond or flat triangle. You want the pointier end of the triangle to face the rear. Then take the diamond and sew it in to one side of the legs. The middle seam of the diamond will be directly under the crotch.
Then sew the legs back together. The pants should be inside out as you sew them back together. The altered pants should appear like the second figure looking up at the crotch with both legs open. You should pin the inseam every four inches to make sure the cuffs will line up. You may have to stretch one side because when you take out the wedge and add it to one side, it may make one side longer.
