TENS unit is a medical device for pain relief. The desired outcome is to reduce pain by stimulating different nerve signals. EMS fitness is also an FDA-cleared medical device but meant for muscle development. EMS fitness is designed to stimulate all the major muscle groups to elicit strength and endurance adaptations."

Circuit training is a form of body conditioning that involves endurance training, resistance training, high-intensity aerobics, and exercises performed in a circuit, similar to high-intensity interval training. It targets strength building and muscular endurance. An exercise "circuit" is one completion of all set exercises in the program.
The best approach to specifically achieve muscle growth remains controversial (as opposed to focusing on gaining strength, power, or endurance); it was generally considered that consistent anaerobic strength training will produce hypertrophy over the long term, in addition to its effects on muscular strength and endurance.
Strength training can increase muscle, tendon, and ligament strength as well as bone density, metabolism, and the lactate threshold; improve joint and cardiac function; and reduce the risk of injury in athletes and the elderly. For many sports and physical activities, strength training is central or is used as part of their training regimen.
Participants in the HIIT group had a decrease in back pain intensity and an increase in back muscle strength. [50] In 2020, a similar study explained the strong effectiveness of cardiorespiratory HIIT in treating lower back pain, when combined with other forms of HIIT or mobility exercises. [citation needed]
Stimulants improve focus and alertness. Low (therapeutic) doses of dopaminergic stimulants (e.g., reuptake inhibitors and releasing agents) also promote mental and athletic performance, as cognitive enhancers and ergogenic aids respectively, by improving muscle strength and endurance while decreasing reaction time and fatigue.
A typical 5k runner might consider 8 to 10 miles (13 to 16 km) of LSD, while a marathoner might run 20 miles (32 km) or more. LSD runs are typically done at an easy pace, 1–3 minutes per mile slower than a runner's 10k pace. The objectives of these runs are to build blood volume and to increase muscle strength, endurance, and aerobic fitness.
