The verb exercise is a regular verb. Exercise has a consonant and a silent e at the end, so you should edd just d to the end. And ed is pronounced [id] in this verb.
-------------------------------
Is this explanation correct? If there are errors, correct them, please.
Change "edd" to "add" -- and the sound produced is [d], not [id] which implies an additional syllable. The whole word when pronounced in past tense is [ex-er-sizd].
Let me know if this doesn't make sense.

Thank you for your correction. I will post corrected sentence.

This explanation contains some errors. While it is true that "exercise" is a regular verb, the rule for adding the past tense -ed suffix is not always simply adding "d" to the end. Instead, the -ed suffix can be pronounced as /t/ (as in "hopped"), /d/ (as in "played"), or /ɪd/ (as in "needed") depending on the ending sound of the base verb.
In the case of "exercise," the ending sound is /aɪz/, which is a sibilant sound. According to the pronunciation rule, when the base verb ends in a voiced sibilant sound (such as /z/), the -ed suffix is pronounced as /d/. Therefore, the past tense of "exercise" should be pronounced as "exercised" (/ˈɛksərˌsaɪzd/), not "exercise-ed" (/ˈɛksərˌsaɪzd/).
