# This Suit Claims to Build Muscle Fast (Exercise Scientist Tests It) Source: https://www.youtube.com/watch?v=KsbY8uSlrVM Recap page: https://rapidrecap.app/video/KsbY8uSlrVM Generated: 2026-02-23T17:33:44.734+00:00 --- ## Quick Overview The 20-minute EMS training session was intensely difficult, causing involuntary muscle contractions and significant fatigue, but it did not equal the intensity or muscle connection of a full two-hour regular lifting session, though it showed promise as a supplement, especially for injury rehabilitation where heavy loading is risky. **Key Points:** - The 20-minute EMS training session was characterized by intense, involuntary muscle contractions that felt extremely taxing, causing Mike to experience muscle fatigue and even biceps cramps. - The claim that 20 minutes of EMS equals 2 hours of regular lifting was deemed a 'pretty big claim' by the expert, who stated it did not match the intensity of a full two-hour workout. - EMS is considered the number one use-case for injury rehabilitation, allowing muscle mass maintenance around an injured area without the high risk associated with heavy loading. - The suit requires skin contact with electrodes to be effective, necessitating wetting the suit prior to use to ensure conductivity. - The expert advises against relying solely on EMS for fat loss, emphasizing that diet remains the primary factor, as EMS is not magic. - For general training, EMS is best used as 'icing on the cake'—a supplement to existing hard work, not a replacement for heavy lifting. - The session included squats, bicep curls with resistance bands, and a plank, all while the EMS machine provided electrical stimulation. ![Screenshot at 00:10: Dr. Mike, wearing the EMS suit, reacts to the premise of the intense 20-minute workout being equivalent to two hours of standard weightlifting.](https://ss.rapidrecap.app/screens/KsbY8uSlrVM/00-00-10.jpg) **Context:** The video features an exercise scientist, Dr. Mike Israetel (wearing a red shirt in the review segment), testing an Electrical Muscle Stimulation (EMS) training system, specifically the Miha Bodytec suit, at an RP Strength affiliated gym in Miami, FL. The central premise under review is the claim that 20 minutes of EMS training equates to the effectiveness of two hours of regular weightlifting. The session involves Mike wearing the full-body suit while performing dynamic movements guided by a trainer, Coach Jenia, while a colleague, Jared, observes. ## Detailed Analysis Dr. Mike tested an EMS training system, which involves wearing a suit lined with electrodes that deliver electrical impulses to contract muscles during exercise. The initial experience was jarring, with Mike describing the suit as a "cyber mech suit" and experiencing involuntary contractions that led to biceps cramps. During the workout, which included squats, resistance band work, and planks, he struggled with the intensity, finding the EMS contractions to be significant. Coach Jenia guided him through the exercises, adjusting settings on the Miha machine. Post-workout, Mike provided his initial reactions, stating that while EMS has upsides, especially for injury rehab (maintaining muscle mass around injuries without high loading risk), the claim that 20 minutes equals two hours of regular lifting is an overstatement regarding intensity. He emphasized that EMS is not magic for fat loss—diet is still paramount—and for general training, it should be seen as a supplement ('icing on the cake') to hard work, not a replacement. He noted that using EMS in conjunction with heavy lifting could offer an extra stimulus, but the intensity of the 20-minute session itself was not equivalent to two hours of heavy lifting. ### EMS Workout Experience - Subject (Dr. Mike) wears the Miha Bodytec EMS suit for a 20-minute session - Exercises included squats, band work (bicep curls), and planks - Mike experienced intense involuntary muscle contractions and severe fatigue, including a bicep cramp. ### Equipment Setup - The EMS suit requires wetting the electrodes with water to ensure conductivity - The machine console allows trainers (like Coach Jenia) to adjust intensity for specific muscle groups individually. ### The Big Claim Assessment - The claim that 20 minutes of EMS equals 2 hours of regular lifting is dismissed as a 'pretty big claim' and 'not magic' - Mike noted the intensity was high but insufficient to equate to 2 hours of heavy lifting. ### EMS for Fat Loss - EMS is not a shortcut for fat loss; diet control is still the primary factor, as EMS does not replace calorie deficit work. ### EMS for Injury Rehab - This is identified as the #1 use-case for EMS - It allows for maintaining muscle mass around an injured area without the high risk of further injury associated with heavy loading. ### Final Verdict - EMS is best viewed as 'icing on the cake' for healthy individuals, offering an extra stimulus when combined with heavy lifting, not as a replacement for traditional training. ### Miami Context - The initial testing took place at an RP Strength facility in Miami, FL, featuring shots of the city skyline and monorail. ![Screenshot at 00:04: Dr. Mike reacts to the concept of the EMS suit, calling it a 'cyber mech suit'.](https://ss.rapidrecap.app/screens/KsbY8uSlrVM/00-00-04.jpg) ![Screenshot at 00:31: Dr. Mike performs a lunge while wearing the EMS suit and resistance bands, demonstrating the active exercise component during electrical stimulation.](https://ss.rapidrecap.app/screens/KsbY8uSlrVM/00-00-31.jpg) ![Screenshot at 00:43: Close-up of the Miha EMS machine console showing various control knobs and exercise icons.](https://ss.rapidrecap.app/screens/KsbY8uSlrVM/00-00-43.jpg) ![Screenshot at 01:05: Coach Jenia explains the CAROL bike, which also features in the facility, to Dr. Mike.](https://ss.rapidrecap.app/screens/KsbY8uSlrVM/00-01-05.jpg) ![Screenshot at 04:48: Dr. Mike is shown in the EMS suit performing an exercise while the trainer adjusts the machine settings.](https://ss.rapidrecap.app/screens/KsbY8uSlrVM/00-04-48.jpg)
