Brief summary: This study aims at investigating the metabolic cost of several fundamental exercises with sandbag. Sandbag training has become a popular training modality that is efficiently used to improve cardiovascular status and physical performance. Despite its widespread use and popularity the metabolic cost of exercises using sandbag remains to be elucidated. Therefore, the metabolic cost of various fundamental exercise with sandbag will be determined to aid the planning of exercise training programs.

Detailed description: Ten healthy young adults will be assigned to this study. Participants will initially undergo a baseline assessment of their anthropometrics, body composition (by DXA), resting metabolic rate (RMR), cardiorespiratory fitness (VO2max), muscular strength \[maximal strength (1RM) and muscular endurance\] and functional capacity. After baseline screening, participants will execute in different days (one exercise per day) one set of each of the following 8 exercise: (1) lateral bag drag, (2) dead bag, (3) shoulder to shoulder thruster, (4) sumo DL with pull, (5) front lunge, (6) single leg RDL, (7) reverse lunge with rotation and (8) clean, in two different conditions: (i) 30 sec and (ii) 45 sec exercise duration, in a random order. Prior to each exercise resting heart rate, blood lactate concentration, oxygen consumption and rate of perceived exertion will be recorded. Heart rate and oxygen consumption (through portable gas analyzer) will be continuously monitored during the exercise and after the end of it, until the oxygen consumption reach the pre-exercise values (excess post-exercise oxygen consumption). Blood lactate and rate of perceived exertion will be reassessed post-exercise.

Eligibility criteria: Inclusion Criteria:

* Nonsmokers

Exclusion Criteria:

* Chronic disease
* Musculoskeletal injury
* Consumption of alcohol, caffeine and any type of ergogenic supplement during the study.
