Wii Fit Plus definitely isn't a serious gym workout, but can be fun and somewhat athletic.
Just like its predecessor, Wii Fit Plus features the Wii Balance Board, a white board where you stand. The Wii Balance Board is a pretty accurate device detecting even the smallest shift in your balance. However, your weight measurement may vary up to one pound. Assisted only with the Wii Remote, the Wii Balance Board makes it very easy to cheat on activities, but just like any workout, you won't get anywhere by cheating.
Individual activities are now labeled with a "MET" scale from one to five. "METs" "measure the intensity of a workout". Some activities, Deep Breathing for example, have a "MET" measure of one. These are very easy and won't get you anywhere in terms of fitness. Games with a "MET" of five, such as Free Run, will really make you sweat.
The five divisions of games in Wii Fit Plus are Strength Training, Yoga, Balance Games, Aerobics, and Training Plus. A realistic coach will guide you through Strength Training and Yoga, making those sections appeal to older players more. Balance Games, Aerobics, and the brand new Training Plus sections feature cartoonish settings with Miis as players. These generally appeal more to younger audiences.
Wii Fit Plus unfortunately focuses a lot on posture and balance rather than actual fitness. The Balance Games and Yoga sections do just that. Some Yoga exercises will hurt after a while, but they still aren't as intense as a workout can be. Balance Games can be fun but will request the player to lean in directions, a very simple setup. Three new poses are added in Yoga, but the Balance Games segment is still the same.
The "athletic side" of Wii Fit Plus lies in Strength Training and Aerobics. Although some don't feel productive, some games will force you to sweat, and the brutally athletic "Free Run" emulates actual jogging very well. Aerobics remain untouched in the expansion pack, but Strength Training includes three new exercises.
"Training Plus" is the largest extension to Wii Fit Plus. This section focuses on both athletics and balance, sort of a mix between other sections. These games are played with cartoonish Miis, but can still be enjoyable, especially to younger audiences. "Training Plus" does not contain any duplicate activities, unlike Aerobics, which treat "Basic Step" and "Advanced Step" as two separate activities.
Limitations and errors in the new additions make this game not only a step forward, but also a step backward. Through experience, it seems the calorie counter is drastically inaccurate. Custom routines are limited to Strength Training and Yoga exercises. The activity selections for built-in routines don't seem to fit their routine's purpose.
Still, Wii Fit Plus can be a fun game, and I would recommend it to anyone who loved Wii Fit or is very lazy.
Pros:
1. Games can be fun.
2. Some activities offer adequate exercise.
3. Graphs and charts record progress well.
Cons:
1. Some games are shallow.
2. "Not your best bet on fitness."
3. You probably won't be completely dedicated.
