Opportunity
Kettlebell users need better tracking for weight, reps, sets, complexes, rest periods, skill progression, and workout density. A specialized logger can outperform general gym apps by matching kettlebell-specific training patterns.

Solution(s)
Build a kettlebell workout log; add programs for strength, conditioning, and fat loss; sell coach-created plans and trainer dashboards.
Background
The niche was flagged with about $40k MRR potential. Kettlebell training is program-driven and progression-heavy, which creates recurring value for logs, timers, and structured routines.
