| Got 5min? Try this, it's much more complete*, engaging the back a lot. Title is a catchy "burn belly fat" but it's more like core training + cardio. It looks scary but anyone (without a precluding condition) can do it. It's only HIIT if you make it so, the key is to pace yourself according to your level, going slow if needed so as to complete each of the 30s. If you can't do the full range, do a partial range, but do that range with proper form so as not to hurt yourself, don't force through it, it'll get better over time. Aim for consistency, not short term record. Side note: lubricate joints before (do rotations and flexing), stretch after exercise: stretching before increases risk of injury. If you really want to stretch before, do dynamic stretching, not static. * doing only sit-ups and push-ups strengthens frontside massively, so front-back is not balanced, further increasing the forward arching position (starting with nerd neck) induced by long term sitting. Front training is important for all-day sitters as these muscles (which should be engaged all along the day but are not) atrophy, but overtraining front (vs back) amplifies the issue. https://www.youtube.com/watch?v=dlantbhXp4Y |
