For people new to either working out and/or eating healthy:
21 Day Fix. The Fix is a great "starter" program. It has 30 minute workouts, 7 days per week for 21 days. All of the workouts have a modifier who really simplifies each move. Workouts range from cardio to weights to pilates to yoga. It also comes with portion control containers that help people learn what to eat, according to their goals. Everyone I know who has done the Fix has had great results from it. It's also a great program to do if you are somebody who does other fitness activities (such as running or yoga) and you want to incorporate some weights into your routine without spending a lot of time strength training. This program really takes away all excuses: short workouts that fit into busy schedules, a modifier so anyone of any fitness level can do the program and a fool proof meal plan that teaches you how to eat. After a few rounds of the Fix, most of my clients move onto 21 Day Fit Extreme, which has 2 meal plans and even more challenging workouts.
For people who want to be challenged in a short amount of time:
P90X3. Most people have heard of P90X. P90X3 is a thirty minute version of the popular workout. It is 30 minutes a day for 90 days. 30 minutes a day means that it will fit into any one's schedule. It will shred fat and build muscle. Plus, by the end you will definitely be a master of push ups, as Tony Horton loves to do those. In addition to the classic schedule, X3 also offers mass, lean and doubles version so you really never get bored with the program.
For people who need low impact:
PiYo. This 60 day program is a combination of yoga and pilates. It's yoga for people who do not like yoga. The live PiYo classes are set to fun music and keep the moves flowing. It really works up a sweat and gets your muscles working without any equipment or jumping. I've seen some great results from the women who have done this program.
For people short on time:
T25. This program is by Insanity's Shaun T, but it is absolutely not as insane as Insanity. All of the workouts have a modifier that you can follow to make the moves low impact. It is also only 25 minutes a day for 60 days. Everybody has 25 minutes a day! I have not personally done T25, but I know people who love it. This will be the program I plan to start with after my next pregnancy when I'm very short on time and need modifications.
For people who want muscle:
Body Beast or P90X. I love both of these programs! They are both 90 days and workouts range from 30-60 for Beast and 50-90 for P90X. The main difference between the 2 is that Beast is solely focused on lifting weights (with one cardio day per week if you chose the lean option) and P90X has cardio, weights and a yoga day. There is also a P90X/runners hybrid online that is fantastic for runners looking to gain strength. It really works well with running since the strength days are only 3 times per week. P90Xers usually move on to P90X2 upon completion (that is the P90X and P90X3 graduate program). Both of these programs can also easily be taken to the gym on strength days. I've done both at the gym many times while traveling.
For people already in shape who want to go beast mode:
Insanity Max 30. This is the 30 minute version of the Insanity program. Let me tell you, it will kick your butt! You might think you are in shape until you try to keep up with Shaun T! In this program you keep track of your "max out" time aka the time where you were no longer able to keep up with Shaun and then you try to improve upon that time during your next workout. It's all body weight so you do not need any equipment at all. I promise you, by the end of 30 minutes you will be dripping sweat.
For people who want to have fun while working out:
CIZE or TurboFire. CIZE is Shaun T's month long dancing program. It's really fun and you don't even notice you are working out! TurboFire is created by Chalene (she's also responsible for PiYo). Think if kickboxing and dancing had a baby, that would be Turbo!! You may have heard of, or taken, the live version called TurboKick. This is the same idea, just in your own home. Whenever I don't feel like working out, I through in a Turbo workout and it gets me moving and smiling. Sometimes you just need a fun way to break a sweat!
