The time commitment required for Jiu-Jitsu can often strain relationships with your spouse. On average, BJJ practitioners can spend 20-30 hours per week training, competing, and staying in shape, which leaves little time for partners and families. Frequent injuries and physical tolls also deplete energy that would otherwise be spent with family.
The intensity and physicality of Jiu-Jitsu can be difficult for partners to understand. Emotional bonds formed through competition and grappling with training partners can lead to jealousy. Fighters may also experience mood fluctuations and changes in libido due to the physical and hormonal effects of training, requiring patience and support from partners.
