You cannot do HIIT or sprint for 5 minutes, as this MUST be paced. It might be a strong dose of a strength-endurance type conditioning, but I'd prefer to see like 30s of max swings w/ 2 minutes rest in between rounds x 7-9 rounds.2) Per your suggestion I'm looking to start doing some HIIT style training (3-4 sessions per week). I've ruled out sprinting since, as you've pointed out, that will mess with my leg recovery from squats. Instead, would a straight 5 minutes of kettlebell snatches (53lb) be an ok choice for HIIT? There is no on/off Tabata type interval, but the 5 minutes of 53lb KB snatches leaves me gassed and wanting to pass out on the floor like a cross fitter.
Congrats on your journey so far man. Keep your head down, lift heavy weights frequently and condition like you're running from a goddamn lion.
