Need something new, try this program to test your toughness in three of the most time proven exercises. It is a lot harder than it looks.

Do a set of each exercise: pushups, pullups, and situps. Round down to the nearest 5 unless your max is under 10 (for example 32 would be 30, 48 would be 45, but a max of 7 would stay at 7). This will be your max for that exercise. If your max is less than 10 you will pyramid by 1′s. If you max is between 10 and 20 you will pyramid by 2′s. If your max is between 20 and 40 pyramid by 5′s. Greater than 40 pyramid by 10′s

So the workout would pyramid up to you adjusted max and then back down, all by a set number. Something like this:

Pushups (max 45) : 10-20-30-40-45-40-30-20-10
Situps (max 32) : 5-10-15-20-25-30-25-20-15-10-5
Pullups (max 7) : 1-2-3-4-5-6-7-6-5-4-3-2-1

You will move from one exercise to the next in a circuit, taking a 1-2 minute rest after all three are done. Then move to the next step on the pyramid. You will continue until the longest pyramid is complete. If you finish a shorter pyramid, just continue doing the lowest amount on that pyramid until you complete the others. So in the above example our workout would look like this:

Pushup 10-20-30-40-45-40-30-20-10-10-10-10-10
Situps 5-10-15-20-25-30-25-20-15-10-5-5-5
Pullups 1-2-3-4-5-6-7-6-5-4-3-2-1

You will be working for 13 total sets taking you about 30-45 minutes depending on your pace. You will have completed 285 pushups, 190 situps, and 49 pullups. This workout is great for doing during vacation, off-season workout, or preparing for military or police PT tests. If you struggle with these exercises then do pushups from your knees, crunches, and chair-assisted pullups. Continue with the easier versions for three weeks, then retest yourself to set a new max on the original exercises.

You should do these exercises three days a week, alternating with cardio days (preferably running if preparing for a PT test). Do this program for three weeks. Then either retest your max after two days of rest, or jump back into your old weight routine. This method is a proven to boost your max dramatically in each of these exercises.
