HIIT stays front‑and‑center
HIIT remains a spring fitness pillar — gyms like Ignite BioFitness are pushing hybrid offerings and new sports courts while analysts rank HIIT alongside longevity and functional training for 2026. New features also argue HIIT can outpace LISS for faster, sustainable fat loss when programmed correctly. ( )
Ignite BioFitness reopened online reservations for its tennis, pickleball, beach-volleyball and basketball courts on March 9, 2026, with booking windows set between 7:00 AM and 7:00 PM. The Menlo Park facility advertises a 7,000 sq. ft. training floor, a saltwater heated lap pool and a climbing wall alongside group fitness and personal-training services.

Evidence syntheses and industry roundups note HIIT’s higher calorie burn per minute and measurable excess post-exercise oxygen consumption (EPOC), which make it time-efficient for fat loss when paired with proper resistance work and recovery protocols. Sports‑science guidance and clinical programs commonly recommend limiting high‑intensity interval sessions to roughly 1–3 times per week with 48–72 hours recovery between intense efforts to balance gains and injury risk. Operators are translating those signals into hybrid offerings that pair short, high‑intensity class modules with wearable tracking and social court play to increase retention and meet demand for longevity‑focused programming.
