Target the arms, shoulders, chest, and upper back while increasing lean muscle mass, reducing body fat, and improving functional strength. Following this program can also result in improved tone, flexibility, and range of motion. This 4 week plan uses 3 intense workouts a week to reshape your upper body and bring about quick changes to your overall fitness level. Different forms and strategies of strength training are the predominate training style in this program, and there is not a single repeat workout in this program - you'll do a completely different workout video every single day.

Workouts range between 24-55 minutes, averaging out to 35 minutes a day. The only equipment you need is a set of dumbbells. As an added bonus, the core (abs, obliques, & lower back) is frequently engaged throughout the very dynamic exercises found in these workouts, so you will likely find that you’re seeing rapid changes in your belly fat and the tone of your midsection, as well as in your upper body. Make sure to take "before and after" photos so that you can see the difference in 4 weeks!

We encourage you to use #FBflex on social media to track your workout sessions, share your progress, find motivation, and connect with people around the world who are following this program. 

Please Note:

• Combining this plan with other programs: This program has three scheduled workouts a week, all of which intensively target the upper body. This means that you will not want to do any additional workouts targeting the upper body (extra workouts for these muscle groups may actually hinder your progress). Strength workouts for the lower body and core muscles would be ideal for 2 other training sessions a week, and activities like running, walking, swimming, hiking, biking, yoga, organized sports, low impact cardio, stretching, etc, would also be great options for those 2 free days each week. You can easily pair this program with our 4 Week Butt & Thigh Program; FBbooty or, to target the core, you can use it with our 4 Week FBabs for abs, obliques and lower back. You can certainly pair this with another Fitness Blender Program, though our more intensive plans that target all of the muscle groups (e.g. 8 Week FBFit, or 8 Week FB30, 4 Week FBmass, etc. - basically any of our total body programs) - may be overkill in combination with this program because they already work the upper body.
