Like that huge gym you contemplated joining, this app is cool but a touch overwhelming. Beyond weight, cardio, and yoga workouts, you can track calories eaten and burned and even use the personal-trainer algorithm to construct a regimen based on your age, weight, gender, and goals.

WIRED 700 exercises plus the ability to add your own. Smart video tutorials.

TIRED Layer upon layer of menus. Laborious data entry to track reps and sets.

This refreshingly simple app does just one thing: It guides you through a 20-, 40-, or 60-minute yoga session. Video and audio tutorials take you from child pose to Virabhadrasana II and help keep your Utkatasana on form.

WIRED Clear instructions. Soothing ocean-wave background option.

TIRED Limited poses. No way to create custom routines. Has banner ads and just one level; ad-free version ($2.99) delivers only one more level.

__P90X__The official app of this workout craze offers clear video guides to ensure proper form, while timers keep you moving from set to set. But it includes only one routine: abs. The rest are sold separately at $6.99 a pop.

WIRED Great video quality and simple navigation. Calendar and to-do list keep you from slacking.

TIRED Necessary "extras" are pricier than the app. $60 complete bundle will exhaust you and your wallet.
