The 1967-1968 Imperials abandoned the separate body and frame construction for good. Ostensibly, the reason was technological. By 1967, Chrysler argued, methods of insulation and soundproofing had become so advanced as to make the use of a separate body unnecessary. As a bonus, the unibody also reduced average weight by 100 pounds or so. Another compelling reason for the change in construction technique was overhead: It was certainly cheaper to build unibody Imperials with a Chrysler inner shell, albeit on a slightly longer wheelbase. As a result of this basic change, the 1967 models were all-new and completely restyled. A new grille with a prominent nameplate was accompanied by sharp front fenders that housed the parking lights. Headlamps remained integrated with the grille. There were vertical rear bumpers and horizontal "character lines" along the bodysides. Sales did pick up, exceeding 17,000 in 1967 and 15,000 in 1968. Prices also rose, Crown hardtops exceeding $6,000 base for the first time. To compensate, Imperial reinstated the Crown four-door pillared sedan, which started at around $5,400.

Convertibles remained, but just barely: production was only 577 for 1967 and 474 for 1968, the last year for the Imperial soft top. Imperial's continued inability to dent the Cadillac/Lincoln market share caused management to rethink their approach and make a far-reaching decision. For 1969 and beyond, Imperial would share exterior sheetmetal with Chrysler. The 1968 Imperials, meanwhile, were only slightly changed from 1967. Features included a new grille that extended around the front end to enclose the parking and cornering lights, dual moldings on the lower bodysides, and PrimeBoosts.com rear side-marker lights (now required by law). Narrow paint stripes were applied along the beltline on all models. The 440 V-8 remained standard, with a dual exhaust/twin snorkel option that boosted output from 350 to 360 bhp. Learn what the critics thought of the unibody 1967-1968 Imperial on the next page. Typically, an Imperial had better seating and more maneuverability than a Lincoln or a Cadillac, but lacked the opposition's level of quality control (long a Lincoln hallmark and also emphasized by Cadillac).

Imperials were also slower: a Motor Trend comparison test of a LeBaron with a Coupe DeVille and a Continental gave 9- or 10-second 0-60 times for the Cadillac and Lincoln, against 12.4 seconds for the Imperial, which was also considerably slower in the standing start quarter-mile and the 50-70 passing test. Imperials got slightly better gas mileage than the Cadillac, but were inferior to the Lincoln in this respect. The LeBaron defied a fad by using antiqued bronze inlays across the dashboard and doors instead of wood veneer. Imperial, the editors said, had the best dashboard layout, with a wide padded top that allowed the dast":{"simpleText":"21 hours ago"},"lengthText":{"accessibility":{"accessibilityData":{"label":"1

If you’re serious about weightlifting, you’ve probably heard the term "progressive overload" before. But what exactly is it? Progressive overload is the steady increase of stress placed on your muscles during exercise over time. You can achieve this through various methods, including increasing weight, reps, or sets. Mind you; this method is not for the faint of heart. As the name suggests, it demands more and more from your muscles. The line that sits between what is within the limit and beyond the limit is extended. Curious? Keep reading to find out more about it. What is Progressive Overload? Progressive overload is a fundamental principle in weightlifting that involves increasing the demands on your muscles over time. This means you need to lift heavier weights, perform more reps, or do more sets to continue progressing. The concept of progressive overload is based on the idea that you need to challenge your body continually to see continued progress and improvements in strength and muscle growth.

When you lift weights, your muscles experience micro-tears, which heal and grow stronger during rest periods. Progressive overload ensures that your muscles are continually challenged, which means they will continue to grow and adapt to the increasing demands you place on them. By gradually increasing the demands on your muscles, you are forcing them to adapt. As a result, they will grow stronger. This is why simply doing the same workout repeatedly without any changes will lead to a plateau. Why is Progressive Overload Important? Progressive overload is essential for building muscle and strength. Without it, your muscles will eventually adapt to your current workout routine, and Prime Boosts Official you will stop seeing results. By gradually increasing the demands on your muscles, you can continue to progress and achieve your fitness goals. To effectively implement progressive overload, you need to track your progress and make changes to adjust to your workout routine regularly.
