You don't always have to jump around doing cardio to burn major calories.  Strength training builds metabolism-boosting muscle and burns even more calories after your workout as your body recovers and repairs itself.  This workout from trainer Autumn Calabrese builds on this principal by adding isometric holds to strength-training moves.  And it's challenging but quiet.  So grab a pair of weights and get ready to build muscles in a whole new way (without disturbing your downstairs neighbours).

Get ready to get your cardio on!  This jumping workout is fast and furious and perfect for burning mega calories in a short amount of time.  But don't worry — we offer modifications for every move so anyone can join in the fun.  The workout doesn't require any equipment, either.  So what are you waiting for?  Press play and get at it!

We love Pilates.  We love HIIT (that's high-intensity interval training).  When Blogilates founder Cassey Ho put the two workouts together, she got an ab-centric PIIT workout.  And it's awesome.  You do each of the seven moves for 45 seconds, followed by a 15-second break.  Do the workout once, or repeat for a total of four times to make a killer 28-minute sweat session.

When Summer hits, you want to feel strong, sexy, and sculpted, and our latest 20-minute workout will do just that.  Trainer Christine Bullock will lead you through a full-body workout where every move is designed to work multiple body parts at once.  It's efficient and fun!  Grab a set of three-pound weights if you have them, press play, and get ready to take it to the mat.

Working your way to the splits, often regarded as the ultimate feat of flexibility, takes time.  Regularly follow this yoga sequence, led by Mandy Ingber, to loosen tight hamstrings and open up inflexible hips and you will be well on your way to maastering the pose.  The splits may be all about flexibility, but you don't get there without strength — so be sure to check out Mandy's new book Yogalosophy For Inner Strength, which explores the relationship between opening up the body and healing the mind, heart, and spirit.
